I have a 94 Gt with several modifications. When I give it full throttle it isent as fast as like 75-80% throttle. Why is this?

is it cutting out or what?

what do you mean by cutting out? Ultimately i wanna know why my car is slower with 100% throttle than with like 75% throttle. I once accidentally cleaned my TB with Carb cleaner and later learned that theres special cleaners for TB. its a BBK 70mm btw

i mean does it feel like it isnt getting fuel by shuttering or anything like that.

no i dont think so, i do hear alot of chatter. What about what i did with my TB, i heard if u do that u could damage its finish and cause air starvation to some cylinders

motorman524

could be tps, maf, fuel filter, fuel pump, loss of fuel pressure, restriction in air, seconedary ignition, lots of stuff man just gotta look. carb cleaner shouldnt have hurt it this one time but i wouldnt reccomend doin it again.

That chatter (pinging) you hear can be your timming advanced to far maybe take it back one

i had a bogging problem and A/F ratio too damned lean, if you have done many modifications you might need to get a wideband 02 sensor and an a/f gauge or go to your local dyno and put in 3 runs and timing and fuel pressure tune it up cheaper than a $3-$400 wideband,, took care of my "bogging"
