Hello i have a d15b1 block with d16 vtec headswap. Arp block studs. Header 4-2-1 dc sport. Gas regulator,adjustable sproker. I have p72 chipped with chrome
Right now i have at 32-34 lbs of gas and my sproker like the fabric but my ignition timing its a little set back. I need to tune that because the car doesn't have the power that has before. I need to know in what grade i need to set the sprocker and how many Lbs i need in the gas reg. in the ignition what time i need to set it up.

It depends.
If you have a pm3b cam gear, set to zero. If you have an obd2 cam gear, set it to -4*

Fuep pressure at idle with no vacuum should be 45ish.

Use timing from a p28 rom. Tune afr.
