Im curious to know because I was punked by a late 40ish man in a 2004 Mustang GT at the stoplight today. By punked I mean he had an aftermarket exhaust and was basically revving the hell out of it next to me. He told me to rev mine but of course my stock GT was no match. Then he asked me to race on the freeway but I told him he was a waste of my time. He only has an intake and exhaust, I have seen his car at the track on display but never actually running. Was I full of crap telling him I would win? I have no expirance with the 4.6, but I do have alot of expirance with my 5.0 at the track and building it up. I know I would slaughter him with the 5.0, but how about my new 2006 GT? I will see him again for sure either at the track or on the street,I perfer to run him at the track. I will be adding a Demolet cold air intake with revised programming tommorow. Any thoughts from people who have more expirance with the new 3v 4.6 or old 2v 4.6?
