Ive also seen a TT Z putting 689 on sharifs dyno put 892 down the road, which is well over 15%, so its kinda hard to tell. Thats why I said its hard to compare numbers on different dynos. I really wont know until we dyno it on another car. Sharif himself told me he usually sees a 10-15% difference, so thats what Ive been going by, and thats in my experience just about exactly what I have seen.
