Need opinions on idle problem...

[KScivic]

So today I got my new ECU from Phearable.net, I plug it in and start the car. It idles real rough, between about 1-2k RPM's. Using the gas pedal is pretty much worthless. I'm thinking it's either running too rich, or too lean. I'm going to pick-up an adjustable fuel pressure regulator, and see if that helps. Which one should I get? Thanks in advance...

Mods:
GReddy 15g turbo kit
Johnny Racecar front mount
DSM 450cc injectors
Walbro 255lph fuel pump

first get a fuel pressure guage before you buy a fpr, find out if your pressure is actually higher than it should be. and if you lean the mixture to make it idle well then it might lose out on necessary fuel up top.

second is the emanage from the greddy kit hooked up along with your chipped ecu?

No, got rid of the e-manage...

What you need to do is bring it to the dyno to have it properly tunned. I'm guessing it's chipped.
