whats up guys?! i just wanted to hear some input on this!! this is my second mustang. its a 99 4.6 5speed and she feels very slow! previously i owned a 94 with a built aod, 4.10's, i/h/e, 75mm tb, afr 164's, e-cam, ford racing lower im, trick flow upper im, 40lb reds, 195lb fuel pump, 3200 stall, and lots more. it was alot faster than this car! i know it was built up and i have beaten several 4.6's but after driving my best friends 02 5speed gt i really wanted to get one for the reliability, 5 speed, and look.. my buddy has accel coil packs, off road x, custom flowmaster single chambers, intake, underdrive pullys, and supposedly a canned tune. the problem is i raced him and he flat out smokes me... its absolutely no competition and he burns half through second when i can just barely chirp it! what's the big deal?! how does he beat me so bad?! he is my best buddy and i know his car inside and out theres no tricks or funny stuff going on here. he only has a couple things done and its that much faster? i have replaced all the plugs and cops. when im in my friends car it has power all through the rpms when mine seems to have a mid range band that it likes. the power straight flattens out at about 3500+rpms. my brothers 04 spec v puts up a fight from a roll! this is rediculous! i originally planned on doing mainly appearance mods to the car but i may have to do something about this first! how much can i gain with a off road x pipe and a tune? the only mods i have are a volant intake and borla catback.
