I didnt say gains wouldnt be significant. And yes I knew that bit of info...good call.
I said they wouldnt be as significant as gains on a 6.2 liter motor without them in the first place.
You honestly dont agree? cmon now...
BTW...did you know that the 2011 GT will make more power than a 2011 GT500 with just bolt ons?
