All numbers look good on Scanmaster at closed loop idle. IAC 15, TPS .44 (Engine running), BL came down from 142 down to 122. Baseline fuel pressure set at 43 with vacuum line off. My question is if I turn fuel pressure down a pound or so it raise BL?

Yes, lowing fuel pressure will raise blm.

Will lower it to 42 later this evening. Thanks

Please dont try and adjust fuel psi for 6 blm numbers. If your plus or minus 10 from 128 your fine.

The car is running fine and I truly didn't want to mess with it but I read somewhere on here that BL must be 128. Thanks for confirming my thoughts I'm going to leave it where it's at adm ride and enjoy the car

Looks like you got it under control now , drive it and enjoy .

x2, within 10, leave it. It changes under different conditions all the time anyway. Just monitor it for way high numbers that may indicate a vacuum leak.

The chip maker takes an educated guess as to how much fuel your motor will need at any given load/rpm. There are many different areas of the program where he makes his best guess. After the car is running for a while,the computer accepts information from the oxygen sensor and determines what adjustments it will make to dial the mixture in perfectly. Perfectly! Because of this the chip burner and tuner can both be idiots and the computer still might be able to dial it in Perfectly! If you lower your fuel pressure,the computer will re-adjust so the mixture will be PERFECT! If you have to see 128 (it will change with the weather), lower the fuel pressure. Or you could do nothing. It makes no difference, generally. You gotta love the computer.

Computers outsmarted us many years ago I left it where it was and car drives perfect
