You should also know that the engine/trans is in my crx. Have a nice day!

boost problem solved....t3 does great, now onto the fuel...after a nice tune last night and got it running good at about 7 psi... me and wes checked the fuel pressure and it was 6 psi too low... 
thought i had it right before but i was wrong.....so now onto a new tune.....

Re: Boost problem. Engine won't hold boost.
With the vacuum line to the FPR disconnected. That'll do it everytime.
41 psi base - 6 psi = 35 psi.
35 psi - 7 psi boost pressure = 28 psi while boosting.
28/41 psi - 68% of the fuel flow you should have.
68% X the 300 whp your stock pump should be able to push = 204 whp before you run out of fuel pump.
Sounds like you're making at or a bit over 200 whp at 7 psi if you are leaning uncontrollably to 12.5:1 AFRs. In truth, the fuel pump's flow chart doesn't manifest quite like that, what it flows varies with the PR it is operated at, but I guarantee it's within 10-15 whp of 204 whp.
I think I have a Motorola 2.5 bar MAP sensor laying around when you want to shoot for a safe 275-280 whp and occupy Robert's place on the foodchain while he's building his CRX.

Re: Boost problem. Engine won't hold boost.
Zekey-boi has a stock turbo, so he isn't getting more than a 5 whp gain off of cranking the boost + tuning, so that's - what? - at most 230 whp that he could squeeze out of his 3000 lb pile of ----, not that he'll ever see more than 200 whp? Slow as death.
Further, that cockmongrel will never materialise in Asheville ever again as my phone would be ringing off the hook + I'd appear within 15 minutes to beat the brakes off of him.
