Ryan recently picked up a used 08 GT500 and brought it over for an FRPP Intake, VMP 2.65" pulley and 90mm idler, and custom VMP dynotune on an SCT X3 tuner.
Stock numbers off the street were about average for the summer.
The modified and tuned numbers blew me out of the water, we usually don't see these types of numbers in the summer when humidity is high, temp is high, and barometric pressure is low. However, I'm going to chalk some of it up to the car having mileage in the teens and being pretty well broken in and loosened up. As my GT500 has eclipsed 10,000 miles I have felt that the numbers have gotten a little better due to additional break-in.
