i have a skunk2 intake manifold, headers, high flow cat, n1 cat back, thats about it. its driving me insane i cant figure it out, and its a stock fuel pressure regulator that bolts on your fuel rail.

Any CELs? Does the power increase at a certain RPM? Is this a recent problem or is it associated with a modification to the engine?

have u looked at your clutch, sounds like its slipping.....

it might be ur clutch problem have u changed it ??

is it bogging?? might be a fuel injector give us more details then we can help you out more

wrong if your clutch is slipping it would rev to higher rpm's like say your going in 1st and step on it and goes to like 8k rpm like in a second then your clutch is slipping if a clutch is no good you would not go slower ur rpm's wud just fly up which results in car reving high but moves no where that's a bad clucth slipping

when i floor it it seems to have less power then if i gradually give it gas. it just started doing this recently.

could i just use some fuel injector cleaner? is there any way i can figure out which injector is bad?

93projectda

have you checked your compression/ mine did the exact same thing

DOHCgarage919

you can see if you injectors are bad when its dark you injector on the plug has a little green light if it glows green its bad if not its good but i wud do this at night so you can see and no fuel injector cleaner will not help if injector is bad

also cud be your spark plugs same happend with mine i changed them all was good but maybe its your injectors check that first or you can buy a set of injectors plug testers to see which injectors work

If you gradually give it gas, does it still make high RPM power? Is there any gasoline smell in the exhaust when the car is warm? (Unburned fuel from misfiring injectors would cause this.)

I'm thinking that it could be your ignition, especially if partial throttle response is fine but WOT is not. Check the cap and rotor initially.
