    If you're ever in Florida you're more than welcome to drive mine and judge for yourself. I'm running a 33.3 tire with 5.29s. I have first hand experience with both and there is a reason why I work with OTT exclusively now. I can put you in contact with tons of fellow enthusiasts who have had both and made the switch. The OTT thread has honest dyno results on their main thread. Also the pricing difference between the two is pretty large...

    I've had both and reviews may vary by set up. Mine is 33s/5.29 Gears/87MM pulley/only added weight is rock sliders and occasionally an RTT. I HIGHLY recommend the YT tune over the OTT. Each utilizes a very different tuning strategy but for general purpose mix of everything (low-speed town/highway commutes/sporty/high and low speed offroading) YT does it better and does what you ask for. I slightly prefer the shifting schedules that OTT has, but OTTs tune isn't built go in to boost nearly as often as YTs which was my biggest issue that strongly outweighed the slight shifting advantage.

    Some portions of my weekend commutes involved mountain passes. In these conditions YT has no issue holding 6th and going in to boost to keep speed and even accelerate up the pass. If you need more it downshifts and stays in boost where it accelerates with no problem. OTT has a weird issue where you can get in to boost in 6th but as soon as you downshift to 5th, all boost is gone and you cant get it back unless you literally floor it or go back in to 6th gear. I've run numerous logs verifying this and it can be consistently repeated. I reached out to OTT to see if it was just a weird miss in the file I received and after some back and forth I was told that their strategy maintains some factory tables for safety which is likely what contributes to the ECU artificially limiting throttle at various combinations of RPM/speed/pedal angle. I personally don't see the logical in that when you can get full boost flooring it but no boost under partial throttle.

    On the flip side I'm not the biggest fan of YT's shifting, my 5.29s and Maggie give plenty of low RPM grunt but the tune likes to hold gears for too long and when slowing down it will downshift to the next gear to soon and be pretty jerky for around town driving. I almost wish that that the non-ECT set up was the ECT setup and there was a milder version for non-ECT that is subdued maybe 30%. But in all other conditions it performs great!

    I have experienced both, I have driven OTT supercharged, as well as tuned my own truck with other tunes before I was supercharged.
    To be completely honest, both are very good tunes. To be fully transparent I am a YW partner. The Yotawerx tune has more acceptable shifting, especially when running around town. Very smooth and crisp. I travel a lot for work, the only tune I’ve ever ran with amazing mountain pass shifting ability has been Yotawerx. Its ability to hold 6th gear and use boost to get up and over passes is second to none. I’d imagine it is ever better on lighter trucks with closer to stock tire size, I am in 38s and Yotawerx does an incredible job. If you are looking for an all around great tune with excellent shifting , ability to hold a gear and something to wake the supercharger up, Yotawerx is the best in my experience. For the same reasons is why I work with them as well. Great customer support.

    Boost, armor, lights, big tires, no savings.
    Curious why there is so much interest in holding 6 under high load conditions. I understand the annoyance of gear hunting. Why not ease the stress on the trans and use the motor more?

    6th gear is almost never used with a stock tune on anything but flat ground. For Yotawerx, the tune has been calibrated to not shift down and use the engine to get up inclines, it’s extremely smooth and quiet. With that said, if someone is pulling a trailer or exceedingly heavy, of course use the gears to take pressure out of the drivetrain. I am 6700lbs with 38s, when cruising 80mph I don’t want constant shifts up and down. Stock tunes are known for goi g from 6th to 3rd or 6th to 4th, with the engine spiking to 5000 rpms. Stressing the tune holds 6th is basically addressing this.

    For me its not so much wanting to stay in the highest gear as it is using the available torque in each gear. The OTT tune lacks in this department compared to YW. Going over passes you can get in to boost in 6th but as soon as you press the pedal down to get in to 5th or 4th, all boost is gone and you have way less torque than you had in 6th. Now you're pressing the pedal down even more, drop to 3rd and the engine screams up the pass, when the YW tune can calmly climb in 6th. When it cant it downshifts to 5th, stays in boost and calmly climbs in 5th. Same if you needed 4th. There's something in the OTT maps that doesn't allow over 100% load at specific RPM/speed/angle so the SC is basically just dead weight at certain times. I'm also on 5.29s so I'm at 2-2.5K RPM in the overdrive gears which isn't necessarily an unhealthy RPM to cruise at.

    Getting technical I've even noticed the YW tune gets about 40 g/s more of air at the peak then OTT at full throttle. Not the full story but makes me think the YW tune produces more peak power too.

    What AFRs are you seeing at WOT? Did you data log any runs?

    There is a reason for everything OTT does. There is a fine line between "feeling" good vs a properly tuned vehicle. There are reasons why the shift pattern is what it is. For additional clarity right from the horses' mouth, email info@overlandtailor.com

    Be weary of some opinions/comments; most are biased/untrue. Some are by people with absolutely no experience and love the seat dyno type approach. Hell some comments are by posters who are new to the tacoma world and just recently were asking the most basic questions about their supercharger purchase... suddenly now they are experts pushing their hidden agenda. Remember, a supercharged tacoma, doesn't mean its a race truck.

    My offer still stands. Anyone in Florida who wants to try before you buy, can drive my OTT tuned maggie supercharged tacoma. Judge for yourself.

    I don't have a wideband but both tunes run under 12.

    At 6500 RPM the OTT tune is pulling in about 280 g/s and the YW tune is pulling 320 g/s. A pretty significant difference I can actually feel as well. It's not drastic but I would say it feels like an extra 20-30% faster at WOT. Significant enough that your passenger could notice a difference between the two. I also have an B9 S5 and the difference in power (albeit still significant) doesn't seem nearly as noticeable as pre-SC. Its' making me get the itch to go stage 2 with the Audi...

    I would want to know. I don't think going much past 12 at WOT is recommended for long periods of time.

    For sure. The stock sensors cap around 11.98 and the logs for both tunes are fixed at that number during my pulls which makes me believe they are both healthy and running under 12. I haven't seen either one at or over 12 at WOT.

    KCLV and knock feedback are both also healthy sitting in the low-mid 20s and -3. Oddly though for the YW tune I do get slightly worse KLCV and feedback at very light throttle when I'm cruising (not even close to boost) around in the 50-60 MPH range. It's gotten as low as 19.5 doing that but will straighten itself out if you go faster or slower.

    I’m getting the Maggy SC installed next month…

    the instructions say to have the latest stock calibration on the truck before flashing the Magnuson tune.

    Currently, I’m not running the stock tune, I have the OVTune.

    Do I have to flash the truck to stock, then flash it with the Magnuson tune?

    or can I just go straight to flashing the Magnuson tune?

    They're concerned about the Cal ID, no so much the tune that is/isn't on the vehicle (as that doesn't matter).

    Thanks for the reply!

    I apologize for noob questions, I'm trying to prevent bricking the truck. If you wouldn't mind, maybe you can help me out....

    I have a VFTuner. I'm wanting to tune the truck myself, in the parking lot right before I give my keys to the shop that will be doing the install. Just so it's one less thing the shop has to do and to expedite the install process.

    I haven't flashed my truck since early 2020... and I don't know a lot when it comes to tunes and what will cause your ECU to brick.

    VFTune worked with me this week; I have the new software installed and my legacy device is registered.

    I pulled my current ID off the VFTune software, it's: 8966304B3100
    Am I safe to install the Magnuson tune?
    Or does this need to be updated?

    When it comes time to request the tune from Magnuson, I have to provide my CAL ID. So is it safe to assume the tune they send me will be compatible/safe to use with out updating anything?

    You’ll need updated to 304B3300 if Magnuson wants you on the “latest”. (Technically there is a 304B3400 now, but I don’t believe Magnuson is providing those yet).

    How do I update to 304B3300?
    Is it a file I download and flash it like any other tune?

    When I update to the new -4B33, will I have to re-register my VFTuner device with VFTuner?

    Again, thanks for your help with this!

    No problem! Happy to assist. :)

    To update to 04B33, you'll need to have the dealer or someone with TS update you using a CUW file. It's the factory Toyota update file. I'll attach it to this post. You wont have to re-register/license your vehicle with VFTuner. You'll be good to go.

    Alternatively, and without turning this into a "sales pitch," you could visit one of my retailers, who would be able to perform the update for you. Ryan is a little ways out, but it might be more convenient to visit someone actually interested in your project.
