Up date on the HP tune, just got my car back from J&M, I was getting Flutter from the Waste Gate Value, They replaced it with a bigger Value, problem solved, my mass air flow sensor is by the Eng. insted of the Supercharger, The Car sounds so diff. much more like an 8. With the IPF tune, they had disconnected my traction control, and here in the N. East, we really need it. With IPF, I made 350 hp, with the HP tune, my traction control is back, and I they were able to get 375hp. and that's on a stingy dyno, when I was in Fl, before the Supercharger install, I had a tune and recorded 270hp ( long tube Headers, low res Cats and CAI) same car at J&M recorded 250 hp. I tried to upload the video from J&M but had problems, his format was for Apple, had no luck unloading to PC. Mike sugessted Meth injection, that'll be my next step. Soo it looks like the LLT"S can be tuned with HP
