Don't go by the A/F numbers on the Sheet, the Dyno's wideband was off by .75 or more +/-.

We were getting bad ignition readings over 14PSI, so we couldn't run anymore boost. Might have a bad CAS. Will look into it this week.

The car did 340 at 9 PSI (Wastegate spring) and 408 at 14PSI. Looking forward to 17 and 19 PSI on pump gas. Then go for broke on Race Fuel.

I am verrrrry happy with the Turbo. The boost comes on nice and quick,

with no lag. Pulls like a freight train. The drag radials are no match for traction.

BIIIIG Difference in drivability over the Holley Blow-Through setup I previously had. Not to mention, more power under the curve.

I am in love all over again.

Thanks Cris.
