Hey everyone, just join this forum recently and this is my first post . Anyways first off I have a 2008 5.7 Crewmax, with recently installed supercharger. Im wondering if any other s/c tundras are experiencing this problem and if anyone has any solutuions that the dealership might not know about. Well I had my s/c installed Saturday and when i picked it up it ran like a champ, couldnt keep wheels from spinning so much power. Well after filling up w/chevron supreme, full tank i might add, it started bogging out after about an hour, but only when i floored it. Two codes came on P0171/4 Too lean bank 1 & 2 . Took it back to dealership and first they said it was tested as bad gas, and than it was still running crappy, so they tested and said new fuel pump was bad. So they replaced it, picked it up on tuesday, ran awesome. That was yesterday, and today its no bogging out like it wants to die, but its a delay and small bogging affect, but def not taking off like it did before. Tire barely spin now. I did take traction control off and set these modes everywhich way.
Has anyone experienced this problem or know any solutions. Im gonna take it back to dealer because it is covered under warranty, and they been really good to me, i just dont understand why this is happening. And no check engine light has come up like last time.
Any help would be appreciated. Thanks.
