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
