I am trying to find how much horse i have at the flywheel according to rx7.com site they have a fuel calulator.I know i can take it to the dyno but my clutch is bad no it F-ing sucks. originally i was told that it was set for med i/c,downpipe,catback,intake,medpipe, good for 12 lbs well my problem is that in primary i am making 14lbs i am not sure in second transition to scare because might blow my engine.thanks for any info,khris

Oh changed your screen name ey?
Wow, I never made more than 12psi on my car w/ that ECU. Well according to my boost gauge, which might be slightly off. Seems I make around 13-14 mm/hg of vaccuum at idle on a rebuilt engine w/ no ports w/ 12,000 miles on it. Seems low, doesnt it?

Hey steve i had to change my name because it was too long and a hassle to type if u r in a hurry.anyhow not ecu made made 14lbs i was making 14lbs before and with my stock ecu, I am trying to firgure out if i need to upgrade to another step because i am making so much lbs in primary.Also u told me it was setup for mods i have mention above and it's good 12lbs whcih is good but since i am making 14lbs i want to play it safe not blowing my engine also my engine and turbos r new only have maybe 1900 mile's because it's a weekend and summer car.my vacuum read 17-18 at idle 750-800 rpm.btw the car is really fast.

Well, my mech gauge is slightly hard to read, but according to PFC my vaccuum is 14.5-16 in/hg at idle 730-790. A little better than I thought.
