I just did my gears, posi, rockers, Ultimate TBI mods, and AFPR. The screw to adjust the AFPR was tightened all the way on the factory setting. This being the lowest setting, I figured it was around 9 psi. I bumped it ump about 1.5 threads or approximately 1 psi. Does this sound about right? I do not have any electronics to tune it in correctly. From my mods(In sig), what fuel pressure do you think I should be set at? Thanks!

 

best way to play, since i know you go there anyhow, is to hit atco on a sunday all day t&t and take two passes, then adjust teh fuel pressure, then take two more passes and see the diffrence. if the car picks up a little mph then you are headed in teh right direction, if it lays down a little then go the other way.
just make littl eadjustmenst each time and as soon as you make an adjustment and it doesn't seem to change or it seems to fall off a bit then you just go back to teh last setting that you got a good result from adn that is the sweet spot.
don't look for a specific number on your fuel pressure yet. all you are looking for is the amount of fuel that your motor wants/needs. you may even find that the best runnign way makes it act crappy around town, just adjust it to a happy compromise.

later
