aside from the normal maintance stuff thats about ill ive done. its strange though coz the car doesnt feel like its soppoused to with all the mods. i raced a 99 mustang today and it was waaay to close for comfort especialy coz his was stock. my car is a 6 spd and has about 90k miles. im thinking it might be a bad clutch but other than the slight lack of power it feels fine. anyone know about how much HP im making or soppoused to be making and have any idea what my problem might be??? i was told that i should be making about 350hp, but with 350 i should be mopping the floor with modified mustangs. PLEASE HELP GUYS!!!

thanks

 

headers will make your car breathe much better and will make you feel the difference with that cam...

 

you might need some tuning as well. That seems very strange. Ive raced several stockish 99+ mustang gt and absolutly walked them. My mods are below. Not nearly as many as you have. I am putting in 1.6rr's and long tubes in this weekend, then it will be a different story

 

push the gas pedal all the way to the floor and you'll go faster

 

yea, the weird thing is that my car is already tuned. and yes i do mash the pedal to the floor. could i be changing gears at the wrong RPM?? at what RPM do you think i should be changing gears in? i usualy do it at about 5700 or so. also, i just got 18 in wheels, but i dont think that would make that big of a differnece. really need the help guys, im dying here.

 

ttt anyone??? i would really love the help

 

PORTED MAF = BAD FOR YOU

Ill bet you money your Air/Fuel ratio is WAY off because of this.

You need a PCM tune as well to change your spark curve, stock spark curve on an aftermarket cam will hurt performance.

 

THat is not the reason for it. He hasnt had it tuned yet!!!

 

Ok ill be getting a new MAF sensor then.whats a good one to go with?? just a stock? also aside from that, where would i get it tuned?? i purchased a lt1 scanmaster,but i have learned how to use it yet. is there a way to find out my air fuel ratio throght that?? is there a way to troubshoot using it? thanks
