Before you can tune anything properly you need to purchase a Wideband 02 brother... dont mess up your investment. I learned the hard way... I tryed to tune by smell and sound lol... that worked for about a year before my ringlands gave away.
370cc injectors are 100cc bigger than stock and not enough to make you run THAT rich. I had 370cc's with boost and it ran for 2 weeks before i got my safc in the mail. I just couldn't and woundn't go beyong 4 grand.
other things to check
-maf
-fuel filter
-fuel pump
-each injectors pulse ( with multi meter )

could the maf be dirty and make it run funny like that??i dont have a aftermarket fuel pump
think that might cause a problem from not having one?i jus changed my fuel filter and jus got new 370 inj from Deatschwerks

well having an OE fuel pump on the 370s would not be noticeable right away. but after a while, the pump will began to strain to operator the slightly bigger injectors
to be honest, i dont know how much a stock pump can take. A walbro pump is only 100 bucks and well worth it bro

the stock FPR is good untill you start to exceed about 400whp
rated at about 33.5 psi with vaccum and 44.1ish psi with line off.

ok jus gotta find a good begginer set up cuz my car keep stallin when i put the clutch pedal in..which is crazy....and it stumble a lil when it goes to idle..its rough..but revs and drive fine..
Your fuel pressure should be set at about 44~50PSI.
Your ecu never reads injector sizes just load from K value, which will then determine your cas value.
If you have upgraded pistons, and are using the stock ecu it should calibrate, and run fine with your compression ratio.
What MAF are you using, and do you know if all your vacuum lines are connected?
Do you have any pics? Camera phone or camera?

Get ride of the stock MAF immediately. High compression engines do not work well with that piece of shiat.
I have an N60 MAF that I can ship to you for $50 "Total" with the pigtail if you want it. Or you can hack up the stock MAF and install the hot wire into a 2.5" pipe. If you have an SAFC Neo the N60 allows for much more use of the voltage spectrum.
Get me some pics please so I can help you. I think you have a couple other problems.
