so here are the symptoms, everytime i try to hit boost, it would cut out. won't let me pass that rpm or whever the turbo is spooling. my setup is a stock gsr with 310cc injector, missing link, fmu, and walboro 255. i will be getting rid of the missing link and fmu this weekend but just want to test and see if my secondary vtec works. i already tried replacing diff. map sensor and unplugging it too. still wont let me hit boost. please let me kno wif you know of the problem

 

1) 310cc injectors are good for max, 210whp. Way too small for any turbo on a b18c1.

2) this sounds to me like an ecu issue more than anything, like it's going into safe mode and preventing you from revving.

but, I wouldn't try to boost AT ALL until you get some bigger injectors and better fuel management.

what size turbo are you running? wastegate? vac lines set up right? bov not leaking?
