Try checking the compression and coolant. Could be a blown head gasket. Or a vacuum problem. Hard to tell from the details given.

 

It's your fuel map, it's got a nasty hole, that's why you're unloading in 3rd. Unlengthen the injector pulse another millisecond, just tune the NOS timing, you'll run 9's





In all seriousness though..... hows your clutch?

 

sorry that was the best way i could explain it but ill try those when i get the chance i just hope it aint nothing to serious

 

if anyone had any more uggestions feel free to share thank you

 

Fail thread. Learn how to write. Go to school.

 

check your spark plugs and change your fuel filter what ecu are you running

 

why dont you go **** yourself bitch **** learn how to write and go to school ****en scrub

 

fuel filter is new and im running a chipped p28

 

Failed again. LMAO>

 

never fails always one *** trying to be an internet tough guy talking **** grow up

 

A P28 running what, Hondata, CROME? Hope it's not a basemap. What's your wideband telling you? You datalogging?

 

Never fails. Always one ***. Trying to be an internet though guy talking ****. Grow up.

Fix.^^

Yes. You need to grow up. Failed, yet again. Haha. "hondegras"? LMAO. Sounds like a 16 year old boy whom just got their drivers license. Run like a champ.

 

what program is in the p28 more than likely if it is a "base map" it will be rich good on wide open throttle but sucks driving on the street my guess is that you fouled out the plugs check and replace with copper ngk and get a tune and adjustable regulator would also help.

 

be more descriptive boss, like when you don't have power, does it sound like misfiring?, or when you floor the car, the rpms don't rise? Any Cels?

for example, my d16y8 turbo would stutter around 5krpm, = not holding boost = blown head gasket
