i have a 1996 mustang gt that has a complete pi conversion and 3.73 gears. a friend of mine has a 98 gt with u/d pullies, o/r h-pipe with flows, and a mac CAI, plus a fewm other little things. i dont know if it is right but his car will run side by side with mine all the way through the quarter and sometimes even pull my car a litle bit. is this right or is there something wrong with my car. i pull him top end but it seems like i should be beating him at least by about a half a car length???any suggestions..(also i have the stock h-pipe on my car..)
