i know hahn's recommendations, but they are general numbers for 5-6 psi...what exact pressures are you 5psi guys running at idle and at full boost...i just begun to realize i never really did a good job tuning mine after my install cause i was so scared and anxious about whether it was going to work well or if i was gonna blow her up. so i want to retune my pressures with a decent gauge...and what can i use to measure O2 voltage accurately (digital, in at least 2 digits) because i dont want to rely on my autometer gauge after i tune it, because im going for perfect pressure and i need some sort of digital voltmeter. where can i get a digital meter that will read under 1 volt increments that is fairly inexpensive (i am buying a voltmeter-equipped turbo timer in a few months and i dont want to wait)
TIA

you can try and get Corbin's A\F gauge......

yeah thats a little expensive though, im sure i could get a normal digital voltmeter from radio shack or something.. i may be wrong but thats why im asking, i like corbins, but i dont need it because my T will have the same thing in it.

Well for me, I'm on the Vortech SFMU 3.64 ratio and shorter spring.

My idle pressure is 55psi, and full boost (4.5psi because of SMIC) i get about 80psi of fuel. Just to be on the safe side.

Also running 7e-11 plugs help out with the combustion alot. I'll pull my plugs in about 300 miles to check for condition.

Oh and I'm using Corbin's A/F gauge. really accurate. Idles hsould be about 0.38. WOT I get anywhere from 0.98-1 volt.
