i have an sir2 (obd-1) motor and just put a drag gen 3 kit on. as soon as i hit boost, my car feels like it chokes. i was told by a local car shop that its running lean. i dont have any gauges hooked up yet. i am running the drag fmu. i upgraded to a walbro 255lph fuel pump and just put on a b&m fuel pressure regulator and gauge. also have a act stage 1 clutch, everything else is stock. boost is stock 7 lb wastegate. does anyone have any idea why my car feels like this when boost comes on. i've only gone into boost for a split second about 4 times. my idle is also at 2-2500 rpm for some reason, maybe my iac valve? before i put on the turbo, the motor was completely fine. oh yeah and i have a new thermal 3 inch turbo exhaust, it smokes a lot sometimes, i dont know whether thats because its a brand new exhaust or because im having problems. any help would be great. will be installing greddy profec spec 2, hks turbo timer, electric egt, oil pressure, and air/fuel gauges. also thinking of going the cheap route and tuning with a vafc and maybe bigger injectors. thanks, happy new years!

 

you need injectors!!!
i just ran in to the same problem with my car. i have the same setup i put in 310 injectors. RUNS GREAT!

 

is your car tuned though? or did u just drop the injectors in and it didn't choke when boost came on?

 

not tuned. just an FMU and missing link.

 

for the funny idle, check the iacv, put those elecronics on asap, especially the gauges, ditch the fmu and get hondata

 

i just put rc 310 cc injectors in and it didnt fix the problem... my car seems like its smoking white smoke (not sweet) almost non stop. in idle and sometimes while normal driving... problems, problems, problems... i need either hondata s100, s200 or apexi vafc2 asap to get tuned

 

what are you using to control the 310s?
