i recently put in a big 16g and ive been running it at around 16-17 PSI on the street. im wondering whats the max i should put it at and what i should tune my SAFC for? heres my current setup

big 16g fully ported, 34mm flapper
full hard IC pipes
3 inch RNR catback
K&N filter
255 walbro HP pump
1G BOV
MBC

i got 550RC injectors off DSM trader and when i went to put them in they looked totally different and looked too shallow to even seal in the fuel rail could the guy have sent me injectors for a non DSM?


and anyway, i dont have a/f gauge but until i get one what should i put my AFC at? i dont have anything to go buy really but i set it at like 4% more fuel in all RPM ranges.
 
well the thing with the afc is that all cars no matter the year is gonna be different.....some can run lean from the start and others can run rich....u have to get either an a/f gauge hooked up or try and find someone with a datalogger...the datalogger would be ur best bet cause u can tune ur car alot better with it seeing that u can check for knock...i would also suggest tryin to get those injectors in....cause ive noticed that most big 16's run better with bigger injectors....cause when i had mine in my car most of the times i was runnin lean at 17psi....
