    Mines done the same things since day 1, on every file I have ever gotten. Replaced the CPS and nothing changed. I get hesitations from idle to about 1800 rpm, its very obvious if you roll second gear from a near stop.

    Mine was also still doing the Stutter thing but at 2500-2900 RPM only, (running 1.05 FOB 91)
    I started running 93 octane gas with that tune and it made it WAY better. Now it only does it under certain situations. I'm hoping the ACIS tuning update that's coming fixes this!

    I truely wonder if its not a fuel quality thing. Try running 93 fuel on the 91 tune. Unfortunately fuel quality varies all over and some end up with older fuel as well.

    That's exactly what I'm doing....this has been the only fix for it. I'm running 1.05 FOB 91 with 93 gas. Now it runs almost perfect but still stutters under certain situations...

    Curious, when you people switched to higher octanes (87-91, for instance), how did you prepare for the change? I understand higher octanes are fine if you're running a lower octane tune, but not the other way around. I'm wondering if I should run a couple of tanks on 91 octane prior to making the switch to a 91 tune, or if it's fine to run the tank to almost empty and then filling up with 91 prior to the tune.

    To switch to 91, I ran my tank of 87 low then filled up with 93. Flashed after the fill up.

    Almost empty is fine. When DTE says 0mi, you have about 3gal left in the tank:

    87 x 3gal / 21.1gal + 92 x 18.1 / 21.1 = 91.3 octane.

    Holy shit, that seems like a massive "buffer"...DTE 0mi but you really have 50-60 miles left...THANKS OBAMA

    Yep. Just like my motorcycle with a 5.5gal tank and the reserve light pops on after using 4gal. I do the mental math to get my real DTE and starting thinking when a good time to stop might be. Ferrying around half a tank of fuel never appealed to me but I understand why others like to never dip low.

    That's what I gather from watching the slushbox shitshow over in the dev thread. As I recall, your truck has behaved similarly to mine, over the last few iterations of the tune at least.
    Imagine that lol, mine's an early '16 with a 04B13 based file, and yours is an '18 with what.. 04B71 file?

    With one hand on the wheel and shifting, and the other hand texting, I have no fingers available for math. Toes would be an option, but I'm concerned about resale value.

    Ha! I may have popped up the calculator on my phone mount a couple times in the past for other math. Range calcs I can do without fingers and toes, which is surprising for me also.

    For the bike, I just divide the Trip miles by 4. It is usually at 160mi, so that is easy. I'll have at least another 40mi before things get real.

    With the Taco, I generally assume 20mpg, so 60mi after the light comes on. The Current Tank Average consistently shows 0.5mpg higher than actual. I will factor that in if out on a trip when passing through towns.

    Yeah, I'm running 04B70 (non-TSB)
    I think most of these trucks run close to the same, but everyone drives a little different therefore notice different things about how this truck drives. For example, if I drive around on flat roads using only 1/4 throttle or less, I won't get any stutters at all and it will have good power and accelleration. However, if I'm going up a hill and I go past about 1/4 throttle I get stutters like it's dropping a cylinder...and it dosen't do it all the time. Sometimes it won't stutter at all. It stutters a whole lot less with 93 octane gas (91 FOB Tune). When I was running 91 octane gas with that tune, it stuttered all the time between 2500-2900 rpm. Even when it didn't stutter in that RPM range, I could feel like the engine felt constrained. I'm hoping if the new ACIS tune that's coming opens that intake valve earlier in the RPM range it will eliminate the 2500-2900 RPM trouble zone.
    The slushbox guys were saying their stuttering was lower in the rpm range than my stuttering so I don't know if it's related or not.

    In the MT Update thread for the TSB, no one reported a successful update with anything but Tactrix. A couple folks tried cheap and mid-priced adapters and got communication errors just trying to do customizations.

    Well that does it! :D

    Older OVT orders came with the dongle as a security device as well as the Tactrix adapter. This required two free USB ports to install the tune. The new Toyota Flash program and a REG key locks to the tuning computer's system ID eliminates the dongle.

    Now, that flash program, plus some other neat features, are combined in FlashManager for one-stop tuning.

    Yes, definitely the old versus the new. There are advantages to each, but I am content being, errrrm, dongless. o_O
