hesitation

[spooled28]

i just puchased a sweet 2004 srt4 about 2 weeks a go , im knew to the srt 4 , i used to own several mustangs fo a 83 to a 2004 supercarged cobra, as far as i can tell the neon has aem cold air intake, . after market blow off valve, and short throw shifter, it registers 19 psi iff boost... most of the time when i take off and go through first 3 gears it runs fine, but somtimes in second or 3rd gear when i part throttle it or just romp on it itll will sputter a little bit then take off, the only thing i have done to it is install nkg irridium tipped plug gapped at .37, let me say it did it before the plug change, and when i did the plug chang i took i out and it ran perfect no hessitation at all , then i noticed the next day it started doing it again....let me say i love this car, im very impressed by it, my friend has a stock 2005 EVO AND FROM 2ND GEAR TO 100 MPH I PILLED HIM A LITTLE OVER A CAR,,,, I WOULD REALLY Appreciate heilp with this.

19 psi on a stock srt is to much with out fuel management . maybe u should get a stage pcm,and injectors,to up the fuel. maybe thats what making it studder a lil. oh an 255 fuel pump

i know its got stock pcm , how can i tell if they arestock injectors, are they like fords and different by colors,,, let me say it only does it at low boost when i romp in it or at part throttle by the time it hits full boost it pulls like a mother ****er, i really wish i had a A/F GAUGE,,

yeah the stock ones on an 04 should be blue i think. ir maybe just get some stg 1 injectors, cuz 19psi is way to much, the mosrt u can push on a stock srt is 17 psi safely. ask over on the srtforums for help they shoul know whats happening with ur car.

thanx for info, i just drove it 150 mi. back from chicago to indy and it has gotting worse before it would hesitate for a split second then take off normal now it hesitates and after it just doesnt have much power, im thinking its the m.a.p.sensor...how can you test it to see if its bad?
