can anyone help me?

[trelz4]

hey sorry to bother you but i have a 95 gt put a gt-40 motor with x heads and a e-cam,track heat manifold,65mm bbk throttle body, c&l 76mm maf cold air intake, 24lbs fms injectors and just got a custom chip burned it is still real doggish out of the hole and it seems like it bounces rev limiter @ 5500rpm which should not be there do you have any suggestions could it link to my fuel pump filter or pressure oh yeah and it is real hard to start and keep running. i forgot it has a header leak could this have anything to do with it? it is getting fixed tomarrow

Depending on how mig the header leak is can cause rich problems. It can suck in o2 and make the computer think the car is running lean and then the comp will richen it out. Also did you get the chip dynotuned or mail order?

 

[trelz4]

the header leak is pretty big and the chip is custom by a guy in my town
dont really know what program he is running but he showed me the program and it looked confusing to me,lol

 

[bjl95mustang]

did he tune it with the leak?

 

[trelz4]

yes it was tuned with the header leak will that create a problem or throw it off?

Thanx Again For The Help Its Good To Talk To People That Knows Stuff Cause I Sure Dont Im New At This Aftermarket Stuff,but Yes The Distributor Made A Differance But Still Alot To Get Finished But From What I Learn From All This Maybe I Will Be Able To Help Someone One Day
