I have a 94 gt 5.0 ho it has msd 6a ignition, msd pro billet distributor, Mac cold air intake, flowmasters, summit off road h pipe, bbk headers(shorty), 4.10 gears, underdrive pulleys , 255 lph fuel pump, and zex 125 nitrous system. Ive done all the work myself and know what im doing but the car just wont run right. everytime i punch it it makes alot of noise revs up high but doesnt go any where but if i put the peddle down maybe a 1/4 of the way it goes ok but not great. but the weird thing is that i just found out if i drive it for a while then turn it off i can get one or two good runs with it and it takes off. if anyone has ANY clue of why this is happening i will try pretty much anything to get it runnin like it does when i turn it off and on. thanx

Sounds like your timing and/or fuel mixture if off. Did you change your fuel pressure when you put the new pump in? I assume you've made some a/f/timing adjustments since your running juice?

i know its not the timeing almost 100% on that cause ive done soooo many checks on that cause thats what i thought it was at first and yeah it is retarded 10degrees i think for the juice and the air/fuel is what i have been comin to but now that when i turn it off and on again it runs real good. do u think the comp could be messin with it or something?? cause if i turn it off then on it runs good but like 5 min later it will be runnin crappy again.

Sounds like your tranny is slipping to me. Have you done anything to help your tranny handle the extra power of the motor?
