This is not my build Im just trying to help the guy. Hes already had one engine blown up by his tooner and reached out for help. So far i think im SOL on injector data and 2 bar MAP data, but ill list everything i know at this point.
Popping at idle, dies when placed in gear. Wideband is currently being installed as well.
94 Camaro with 97 harness and P01 pcm from 02 yukon OS 12212156, LT1 stroked to 383 yet cyl displacement in tune still shows 45.5178 (6.0), -30cc dish pistons, M122 supercharger, 0280158279 injectors (cant find data and the tuner changed the flow rate and nothing else, but set flow rate for non-ref system when the car has a referenced system), new fuel regulator installed a couple days ago, 2 bar MAP 307008 FAST, yet the tune was never changed to a 2bar OS and the owner states the tuner installed 2 MAP sensors in remote locations. Walbro 225 pump that was recently changed and fuel pressure verified yesterday. NO MAF by request of the tuner but he never failed or removed it from the tune. No EGR, FAST 6000-6300 ignition box.
Including a few videos for reference along with tune and log. If i forgot any pertinent info then just ask and i can find out. So, other than converting to a 2 BAR OS does anyone have some suggestions? I tried a few changes and it didnt have the intended effect, so i thought id just get some advice.
EDIT: cant upload the videos, but he has 2 remote mounted MAPs. vaccuum from manifold goes to one, which leads to another and it looks like theyre tied together as far as vacuum lines. The electrical from one map goes from the sensor to the ignition box and coils?!?!
