Mad Hatter
Gotta go Faster
Helping a track buddy with a S550 GT get a AED tune and Shawn found too much False Knock to be able to tune it. Went through the videos Shaun has on you-tube, but so far have not found any obvious knocks. Any ideas of where it can come from apart form the actual exhaust?? Though it might be the 1 and 7/8th header but does not have any sign of touching. At least we learned that this is what a false knock looks like!!
