Hows my settings of Fuel Pressure? Timing? Running a little rich I think.

[91LX_5L]

Well I installed a AFPR and bumped my fuel pressure up to 40 at idle (all connected). After doing so my car backfires when I rip from 1st to 2nd gear (I mean go up to 5500rpm and slam 2nd). Now I had my timing at 10* because I had a tweecer that I was going to use, but I sold it, so last night I put my timing up to the popular 14* and it took it easy, no detination with 91 Octaine and seeems to pull a bit harder.

Anyways do you think I should turn the fuel pressure down a bit to lets say 38? Also should I put my timing up a bit more?

Thanks in advance,
Matt

"up to 40 at idle (all connected)"

By this I hope you dont mean vac. line connected? Never set the FP with the vac. line connected to the reg. Always remove the vac. line when setting the FP.

Stock is 38-39.5.
