i have a JDM h22a obd1 on a 97 prelude everything converted to obd1 even fuel injector using resistor box. i have a smsp header, intake, exhuast and chipped neptune ecu. what psi should i be boosting? im using a B&M fuel regulator

 

^ Who put the Neptune system in your car? IMO, you should let them fine tune the psi on the fpr.

 

i bought the ecu off a guy with a prelude and just put it in my car

 

I searched from boosted-hybrid.com. I couldn't find any neptune tuners around you. Theres one person in San Fran and Locash in Arizona. You might be running rich or lean. My best recommendation is to shell out the cash to have the car tuned. Maybe you can call tuners in your area to see if they can adjust the air fuel mixture.

 

can't find a tuner around my place so need to know a safe fuel PSI with the mod i have right now.
