When you are dropping pressure are you seeing your duty cycle go up as well?

Hey, Chris, if the injectors are smaller the fuel pressure should stay up even better right?

I mean, I get that they may not stack quick enough for a full fire because of maxing the duty but the pressure should still stay up right?

BTW, How do we measure duty cycle?

I should not be out of injector. The car has less then 550 rwhp. I've tried to find a pid for duty cycle but have had no luck with the sct.

I've put calls into fastlane for support. I've heard conflicting stories where a value has to be changed in the tune or it's an early vin problem happens to 1 in 100.

Correct, If your injector is to small and fuel pump is large enough/flows enough then your fuel pressure should not drop. In the pids section on HPtuners you can log duty cycle for your injectors.

The max power using a stock pump is around the 550rwhp pump with a supercharger. The supercharger takes some HP as well to make the HP so generally a supercharged car will require more fuel than a turbo for the same hp. I know you said you have a BAP, are you sure it is operating properly under boost?

I noticed in your signature Janetty built the car. Have you called Ted and talked with him about this as well?

I'm at 573 RWHP on stock pump, with no BAP and #66 injectors with the Vortech V3 complete kit with no drop in AFR or FP at WOT.

Just sayin

Granted, I will upgrade my fuel system before adding more power.

Yes the stock pump is good to 550 which was dropping to 48psi. My problem is the fastlane which should be an upgrade even over the zl1 pump is also dropping to 48psi. I have disconnected the bap with the fastlane pump but even connected it was dropping.

I leaving Ted out of this because I purchased from a forum member and it's a pump he doesn't carry.

Fastlane does say it's a plug and play.

If your dropping pressure even with a BAP, you have another issue. What is your Voltage doing under WOT. If your voltage is dropping your pump output will follow.

EDIT: to the original poster sorry to hijack the thread.

I wonder if my BAP is not working?

How can I check?

Measuring my fuel pressure from the OBD and WITH the bap it drops to 48psi.

That I will have to check. I'm using the SCT to log so it's trial and error finding the correct pid.

It just doesn't make sense to me.

Unhook your BAP. If you get the same results its not working. Do you have it wired to be on all the time or does it come on with boost?

Mine comes on when the pressure goes possitive.
