You're supposed to do it on hot right from the getgo, show the trans the highest amount of power it will ever see, and it adjusts the settings accordingly....then you can 'detune' to whatever you want and never look back. i personally did not do a relearn....i did'nt approve of the process on a new truck/trans. It has learned on it's own but only time will tell if I should have listened to the boys that designed the software.......but so far so good, trans has been flawless.

if you don't reset the taps it will flare on the shifts pretty bad (if running on hot) lower settings wont be as bad. it will still learn the added power but not as fast.

Yah but no way I'm throwing it on HOT and going WOT to 80 and draining the fuel rail/filter and having that issue without a lift pump.. I'm with you and so far so good with the shifts in wild and letting it relearn, but its only been a day or so. I'll see how it adapts over the enxt few days as well. Hell, I don't eve have anywhere around me I can do those runs in S. Florida near the ocean! I'd have to go out west somewhere!

Ken (or anyone), whats your take on this. Have you noticed (when stock) that when you put the truck in drive the transmission revs really high for a while and then drops down after you've accerlated for a while. Is that just an Allison thing? And with this DPF delete and tune, does that go away or is it still there? I havent been able to tell yet but I've been wondering what thats all about.Almost like an overdrive...

Mine never raises rpm in drive. Haven't heard of that before.

Just when you go from park to drive for a little bit. It rev's really high and then you feel it settle in. Never noticed that? Anyone?

I have been deleted for 5 days and am already used to the added power I have 4 questions for guys running the delete.
1.)How much boost is your H&S moniter showing at wot on performance aka HOT?
2.)Have you tried the 0-60 or 1/4 mile test available on the black maxx and mini maxx? If so what are your times?
3.)Has anybody done full throttle acceleration from 0 with the TC off? Does your truck limp trying to shift from 2nd-3rd or 3rd-4th to where you have to let off and get back on it to get it to go?
4.) This is my first tuned duramax, always been a gas guy before this. How are these LML's with an h&s on hot compared to lmm,lbz,lly,lb7 also tuned with stock turbo with ppe or efi live? I already know stock the lml's have more power.

#1- I can see 30-32, but it's hard to get there.
#2- Haven't tried that.
#3- Truck only 'limped' before adding a lift pump.
#4- Only diesel I've had, but i have driven a tuned LBZ and it felt different because it weighed about a 1000 lbs less....it felt more nimble and quicker.

Think ill opt out on the procedure by h&s too

It's recommended but not required and ya I don't want to limp or drain fuel rails soooo ill continue to drive normal and let it take its time. I don't have any hard up/down shifting when I get on the pedal a little bit

As far as I'm concerned unless someone can prove our ideals of tranny learning are crap!!

Does H&S state that the tranny needs to be relearned? I didn't see it, or did I just miss it in the mini maxx manual?

When your truck 'limped' before you added the pump did your truck show any codes for fuel rail pressure or anything like that?
