Allright heres the deal. i was currently running 440cc injectors but now i upgraded to 750cc i know i have to get it tuned first but its gotta make it to the tuner first. i used the o rings that came with the injectors. the ones that go in the intake manifold. i think they might be too big because i have to really force em in there is that right?? when i took my old ones out with other rings they were not that hard to put back in but these are. i was able to get em in there somewhat but i dont know if this is causing my car to run shitty, i cant rev past 4, 000 without it sputtering. what do you guys think???? b20 vtec gsr head , thanks

 

o-rings have nothing to do with your idle, its the bigger injector, your ***** running rich as a pig, causing the stumbling, your map is fpr 440s not 750s

yep.. with new injectors you really need a new basemap if theyre a lot bigger.

get it tuned and problems will be solved

 

so put the 440's back in drive it to your tuner, put the 750's in while your there and have him tune it

 

ahhhhh, i thought so, prob is i sold the 440 for the 750, i totally noobed it up, lol , time to tow, i guess, thanks guys
