Ok to start off I have a 2003 pontiac sunfire ecotec turbo'd.
I just got it all running good but when it boosts up to 9psi,
I get a little bit of hessitation in the higher rpm ranges. Now
I was just wondering wheither that would be because I need
bigger injectors or what would that be from? If anyone has
an suggestions please feel free to reply or E-mail me at
paauw@netrover.com, I am all new to this boosted thing but I
do know the basics and I am just wondering how to eliminate
this hessitation?
Now Boosted, I'll NEVER Go Back ! ! ! ! !
Project Yellow Blur Is Under Way ! ! ! ! !
What are your AFR's when it hesitates?
more info on what you have would be VERY HELPFULL
we cant help you with info on your set up
wide band o2 , larger injectors and something to control fuel under boost are a must
yea how about telling us what size injectors you have? fuel pump? any ways to tune?
if you dont have a wideband, get one... before you drive your car again.
like the others said. we need more info on what you have to help you.
what are you doing for fuel upgrades?
what turbo size are you using?
"Growing old is mandatory. Growing up? Definitely optional."
do u have the stock spark plugs? have u regapped them? i had that problem before, i guess the spark was getting blown out and the car was missing. try closing the gap some on ur plugs
***Need an '00 or up Cavalier shell...stock prefered...email me and make an offer***

dear lord man. you need to be careful. this could not only be dangerous to you but everyone eles on the road.
if your getting starved for fuel your goinig to feel sort of a drag. its kind of like your letting of the gas, with out letting off the gas.
this is really dangerous to you motor a lean condition wont be felt unless your up there. for instance if your showing say 17 you probably wont feel it, but anything after that and the car will drag. if this keeps going your going to have a really bad day one day.
mind you, there could be a number of reasons. hell you could be going way rich. all Im saying is be careful and do us one hughe favor. tell us everything, and anyhting you can about your setup and car. and im sure will find you an awnser. but please god take it easy.
