im wondering how much i can boost with the stock civic inectors.Im trying to figure out why my safc2 dont respond well to my stock injectors under boost.

the computer sees posative manifold pressure and that throw's a check engine light and goes into limp mode

you're not supposed to hit boost with a stock computer and injectors; Thats a really bad and stupid thing to do; quit half assing and get some real management;

yes i do go into limp mode but i also have the missing link installed so theres no way the map will see positive pressure. I used my wideband and found out that under boost the a/f would lean out to 18. The safc is just for the meantime before i get Uber. Im assuming its the stock injectors that causing this. I previously had the dsm 450's installed but it ran like crap so thats why i went back to stock.

18:1 under boost is bad news; if you haven't broke something already it will break soon.

Get real management; go d/l crome or uberdata and set that **** up. Also research what to do for fuel managment; obviously you didnt do something right if your car wasn't running right with 450cc injectors
