Yea, at proving grounds even. That's why I cut like 3x 1.6' 60' times and would only run a 12.3 or so...the car was only running like 24psi up top. Then I added more WGDC in vein and got it up to 29 or so and ran several 11.8's, but the car would just fall on its face off the line as if rpms dropped below 5500 or so the car had zero power.

Also why I had a miserable time at autoX, no boost under 6000 = no fun!

Glad to hear your turbo is healed, Scheides.

Since Murlo's car appears to be on the fritz, I'd welcome some T&C on the cruise if you're up for it.

Sweet, glad this fix has you rocking again!

I vote leave it running 39psi
