Regear VS tune

While regearing does help the torque application… the shift logic still sucks even with gears… that’s why you need to tune it.

It’s like having a 75” 4k TV but if you’re still getting live TV from your rabbit ear antennas there’s no point.

So much digital application and logic applied to these trucks that teaching it how to drive is very important.

 

not quite. The tune changes shifting behavior drastically. I can hit 90mph in 4th with ease lol

you can also tune for different tire sizes which also can angles shifting behavior.

the biggest win with the tune is linear throttle and a confident consistent transmission behavior that replaces the garbage stock transmission and engine tuning

 

Well, the problem is shifting down to 4th when trying to go above 70 so idk why you would want to go 90 in 4th. I wanna do 80 in 5th and 6th without having to go down from there. Only rehearing is going to achieve that.

Tuning for the different tires makes so little difference until you hit 35s, which barely any of us have. Also, once you're on 35s you better already have some 5.29s.

the only wins really for the tune is the linear throttle and the added power.

 

thats exactly it. When punching it, the tune keeps gears better for the specific use case. When cruising it does what it should do to the best of its ability. It shifts when it is SUPPOSED to shift when tuned

gears help a lot because the torque is greatly increased which is where power to weight ratio shines, but the tune is smarter than gears. Pedal input is different through the curve and when it’s down it holds gear…if slightly down, completely different, yet linear experience

yes to 5.29’s if above 33’s IMO.
In the newest tunes, tire size does make a difference in shifting if only 1” difference. I’ve tested this towing and not towing. Don’t get me wrong I am advocating for the tune, but also gears.

the manual has a lower gear ratio stock than the automatic does with 4.88’s…so yah, gears are good

 

You know, that was kind of my point as well. After the 5.29's I thought what if a tune makes it that much better? Guess what, it did!

 

That's an interesting perspective. I got the tune when I was still stock and it felt great. Then I got 60lb e-rated 285s and it felt not fine. Then I got 5.29's and bam it was better than ever.

I assumed if I'd gone 33's and gears to begin with the tune would've been unnecessary. Your experience makes me think I was wrong. Can you describe the feel before and after the tune post-gear install?

 

That's my main reason for doing gears first, lol. I also have e-rated beefy boi 285's. But yea, seems like most people are happy having done a tune first, I just know it would require a re-tune after gears which means more money and that makes no sense to me. Well, regardless, I know what I'm feeling and how the truck drives and it's good to have done the lift and tires first to know what's more important for my use next. I still don't believe anything is going to convince me that it's better to do a tune before gears. Maybe a lower level with less weight. I'll be adding bumpers and probably going up slightly in tire size next time too. It just all seems opinion based to me - which is why my initial post said "why not both?". Our trucks need both.

 

I bought all the vfTuner stuff so I could just flash back to stock and see for myself but that's unlikely to happen.

 

After gears (with 285/70 R17's) it still felt like it was never in the right gear. I have a 15 mile commute with over 1000' in elevation change with 2.5 miles of 7 degree grade. The trip home (uphill) was a killer, up shift, down shift, up shift, down shift, etc. With the tune, I can hold 60mph in 5th gear almost the entire time on the 7 degree grade. If I need to overtake on my side of a four lane road, I can give more throttle, drop to 4th and get it done, then it's back to 5th. Kind of like a modern automatic transmission is supposed to act

The only anomaly I notice is in one small stretch of (fairly steep) down hill, if I brake to allow engine compression braking it drops from 5th to 3rd, when 4th would be appropriate. I need to reach out to @PapaRee or @TWTaco about that strange behavior. I'll admit, I probably don't have the typical commute, but it sure tests a vehicle and its behavior.

 

Still, a good path to take considering the cost.

 

BLASPHEMY!

Still not as bad as a CVT. Very, very close though.

 

I'm just on this vftune 2.0 but if I don't hit the ECT button I still get that same feel like it's just trying too hard to keep the lowest rpm possible and upshifting prematurely. On ECT the truck feels amazing, just right

 

2.0 unedited doesn't adjust as much as people think. Time to make edits!? Lol

 

how many miles on the tune where you had it drop to 3rd going downhill? I had this happen once but only when the tune was new < 500 miles

 

bro…

you need an updated tune. ECT in the new Nexus or KDMAX tune is unlike anything in the 30+ tunes I’ve tested. Sheer distinct power

 

Man I'm not tryna pay any more money on this tune. I'll wait another 3 years until they release the ultimate tune and see what's up then. I've spent enough lol

 

Over 500, probably 700 and it see's this stretch of road every day and does the same thing every day. Lately I just let it coast down the hill at 60+ and don't worry about it.

 

PM…just because lol

 

Question, I just upgraded to 265/75r/16 from stock 245s. I noticed it is a bit sluggish, so I need to change to a higher gear ratio to compensate? What do you guys suggest, I’m new to this.

 

Tuning is by far cheaper and will allow you to correct the horseshit transmission logic the 3rd gens have. Doesn't much pay to regear unless you haul/ tow often or go 35"+ on tire size. Even then tuning helps out a regear a TON!
