Hello, I have a 2005 Ford F150 Lariat with a 5.4. I have an aftermarket Airaid CAI. I recently superchiped my truck with the flashpaq tuner. I also did a CAI tune but had no way of adjusting it in any way. My truck was aggressive as anything and when I hit the pedal at 30-40mph, it screamed and hit 5000rpms (this is with having 35' tires on and a 6inch lift). Recently however, my truck is not doing this. It feels a lot more sluggish, I still have the same tune in it however. Does anyone know what it could be or what I should do or check? Any help is great! Thanks
