So I'm not sure what the deal is and maybe you guys will have some insight or advice before I take it to the dealer. When my auto transmission shifts to 3rd gear and reaches 3k rpm it immediately looses a couple hundred rpm as if I let off the accelerator just a hair then the rpm's climb right back up. It's really strange and has been doing this for a while now or at least I noticed it a while ago. I'm running 37" tires with 5:13 gears and a Superchips Flashpaq. I've tried different tunes and they all do it. The only thing I haven't tried is going back to stock without a tune. But my understanding is that the Flashpaq doesn't reprogram the transmission anyways is that correct? Thanks guys!
