[QUOTE="LavaSlide, post: 16523265, member: 123838"] Yes I do have a new tune from Lund. They have looked at the logs and something else is going on. I have a friend that has a dyno and we did a pull just after I bought it. It made 639hp/701tq letting out at 5100. It came with 1/2 tank and they put 93 in it. At the time the dealer and I did not know it was E85. I am now guessing it was E85 because after 2 tanks of 93 the car really did not run well. Here is my post just after buying. [URL]https://www.svtperformance.com/threads/new-to-me-shelby-gt500.1191274/[/URL] The car runs great until I hit 12lbs boost and above. The orange stripes are gone now! [/QUOTE]
