First thing is first though, I gotta get my pressure to stay up. It drops to 48 psi at WOT and at only 7 pounds of boost. |

Can you read fuel pressure with a scanner on our cars? would save me some money i already have HP tuners and could just use the scanner.

Yes, Under your PID's there is: Desired Fuel Pressure Injector Delta Pressure Requested Fuel Pressure Fuel Pump Commanded DC. Scan all 4 of these and this will give you the info needed for you to tell if your FP is dropping. Chris |

I have a ZR1 MAP sensor coming and plan to install once I get the ZL1 pump and perform that install. Can I drive safely to the tuner with the ZR1 MAP and have him perform the tune or do I need to install the sensor at the tuners to avoid driving it without the tables in the ECM corrected?

I would get rid of the bap and switch to the ZL1 fuel pump and upgrade the injectors to 80's. Chris |

I'm another that is dropping to 48psi. I found a good deal on the fastlane pump and put that in instead of the zl1. My fuel pressure is still dropping to 48Psi. This is with just the supercharger and bolt-ons
