What's up everybody?! Has anyone ever installed an adjustable fuel pressure regulator(AFPR) on your EFI truck? I'd like to know if someone has already made a fuel rail adaptor, or how people deal w the OE regulator hole in the rail.
What solutions have people come up with to overcome the OE rich fuel settings in the ECU when your truck was all motor? Piggyback? Standalone? Some custom setup?
My dyno guy thinks I can wring a bit more power out of the motor if I can lean my A/F a little. What do you think? Here's a link to my baseline run chart.
Thanks for your suggestions!
