Upgrades not running right

[1badgstdude]

Just bought the car 95 gst. I put on it a greddy FMIC. Greddy BOV havent recirculated it yet(GOIng to though). Apexi 3" downpipe, Apexi catback, EvoIII turbo, Evo manifold, And evo o2 sensor housing. and also a intake. I put all this on and know my car is sputtering real bad and is idling real high at about 2000rpm. Where should I start? I thought it could be the plugs and wires but changed those still doing it.

PLEASE HELP!

have you checked the throttle screw?

A vented BOV will cause the problems your having. Also do a boost leak test.

Is that all the mods done to your car? We need a full mod list.

I have the stock fuel pump and injectors. I bought the afc, 255 fuel pump and the 650 injectors. Still in box havent got to that yet. I was thinking of taking the car to Road race to put on. I just did the bolt on stuff to try to save some money.

sounds to me like you have some fuel supply issues. you really should have installed the fuel pump and injectors first.I have the evo III set up and 680 injectors which on stock a/f and timing ran like siht. but thankfully i have dsmlink. but anyways, to me with all that intercooler work and exhaust upgrades you fuel curve is going to definatly be off.. my younger brothers gsx has all the same work but still on stock t25 and he's running pig rich. I dont know if this will solve your problem but it's at least some thing to think about.

Well here your problem then. You just put a FMIC on and didnt do a boost leak test after. Why not just make a boost leak tester, it will cost you less than $10 to make. They are key when owning a DSM. Check out www.vfaq.com. It will show you on there what you need to make your own.

Boost leak test. Go to your local WalMart or hardware store and get either a small compressor or a decent sized air tank (which you can fill up at your local gas station for free). Then build the boost leak tester and have at it. This way you can do it yourself anytime you want. My guess is you probably have at least a few leaks, with a possibility of some at your couplers and the bov.

Recirculate that bov ASAP!

Before you install your fuel mods, get an AFPR as the 255lph will overrun your stock FPR. And get a rewire kit for the fuel pump while you're at it.
