    You need to check that your RRFPR is actaly rising. A few people have had issues with it not rising including myself. your idle will be rough coz you are prob rich due to big injectors and the highr than stock fuel pressure. R88

    What are your RPM's ? Dont want to be on the limiter because it cuts fuel there.

    Good point if you are above 8100 at WOT then that will make you lean. R88

    PUT YOUR RFPR AT 69 PSI. WHAT IS YOUR AIR TEMP? YOUR STOCK PUMP IS GOOD TO 74 PSI. SEE WHAT THAT DOES. YOUR IDLE IS NOT GONNA SMOOTH OUT WITH THE 50s, MINE DOES THE SAME THING, IDLES AT ABOUT ABOUT 1650 TO 1700.
