i set up my crower 403 LS cams at +2 intake and -3 exhaust and i want to know what fuel pressure I should i set it at before i abuse it. (don't want to detonate). I got the fp at 38 psi right now (hose attached).

I know i need to go to a dyno to tune properly but money is a factor right now.

anybody dynoed their car with the same mods and can give me an estimate of the fuel pressure i should use? thanks in advance

2 1/4 in. cat
2 1/4 inch pipe and muffler
3 in CAI

 

38psi is fine............you dont need to worry about dentonation with just a set of cams.

make sure you set the timing back after you adjust the intake cam. everytime you move it the ignition timing changes.

 

38PSI should be ok. But with new cams, I would suggest getting more fuel enrichment to get the maximum benefit out of the cams. A S-AFC would be a good addition. Just get it tuned properly.
