When i did a bassani o/r x on my 2003 w/magnapacks, i kept getting the CEL. Even with MIL's and a SCT tuner...

What do you guys do?

Did you pull the codes and what were they? It couldnt of not had enough backpressure and it might of been messing with the exhaust valves. Chris

when i put the sct tune on ... it jacked up my car, codes were fuel rail failure, and something else i cant remember... but my car wouldn't start sometimes, and when i took the tune off the cel would keep coming back on, so i would have to plug in a just delete the code until it came on again...

What do you guys do to if you run O/R?

we dont have to worry about the OBD2 bullsh1t....

those are the high points of the 5.0 no CEL from o/r mid pipes (no MIL emilinators required)
