Is the majestic turbo upgrade the standard to4e - 46 trim with the slight clip on the exhuast wheel?
Overall peak number seem's a little lower than I'd
expect, but it looks like there is a lot of area under the
curve. You're also on the stock IC...which especially on
an upgraded turbo can hinder peformance as the air
becomes overheated. I think you have a lot of potential
power to extract....
Just curious what is your ignition timing set to? Stock?

ReTED,
Mostly because the graphs are scaled differently than usual. The total scale on A/F is spread out over most of a page instead of just at the bottom.
casio, what is the vertical line test?
gsracer,
Yes, that is the correct upgrade.
Ignition is retarded 3-4 deg via the CAS. Also, I run 5 gals 100 octane to 10 gals 93 octane when running over 8 psi. - This is only done on a road course anyway.
I am looking for a high flow top mount. I have the IC insulated with some high tech injection mold insulation that keeps it pretty cool, but I need better flow.
The profec B comes on to 6 psi immediately, then holds to about 3000, then slowly builds to 9 psi by 4500.
Current settings are 0 gain, 8.2 start boost, 35% duty cycle. The slow build is intentional. I can set the start boost to 8.5 and get faster response with a 0.5 to 1 psi overshoot, but I want the boost to come on progressively to make use of it on the road course.
