Got my LLY juice, exhaust and intake installed yesterday, took for a short drive and have a few questions. At first felt like no power gains at all(must have been cold still I guess) Tried a few launches from a stop and finally felt power gains but seems to shift funny and loose power before shifts. Can anyone who has run a few miles give me any suggestions on how to get the truck used to the chip and setting suggestions. I only have 500 miles so I wanna stay safe for now, does the tranny have to relearn for each setting?

From what I've read, Yes, the tranny has to "relearn" shifting. Don't go above "3" on the Juice without trans mods... I'm a Newbie too, only 210 miles on my truck and itchin' to install my stuff! Patients... Patients... Take deep breaths...

Dreamin is pretty much right on. If you didn't feel it right away the engine was definately not up to temp yet. And the shifting is all about letting it learn. I didn't let mine learn quite right but the right way is to move it up a level every day or two. And then basically leave it on the same level all the time and it will shift its best.
