You are quite right. And I will but I have no one here that can tune it.

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.

What type of FI do you have? What fuel pump are you using.

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.

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?

Mine are the stock TVS2300 Magnuson injectors.

Stock fuel pump with a KBB BAP.

I'd just drive it there with the existing sensor. You can swap it out in 5 minutes when you get there.

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

ZL1 pump is coming.

Injectors, gonna be a bit. Mainly because I have to find someone to tune them when I swap them.

Gonna run a ZL1 Pump with my BAP on my setup. I'm loosing fuel pressure as well.

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

Really?

Reading from the rail or from the OBD?

Reading from the OBD. I do have the ZR1 map sensor. I was confused also.
