Damn short time is killing me!

Update with the turbo on. I can now brake stall up to 3000 RPM and build 5 psi off the line. I ran another 1/4 with my scan gauge and it showed a 13.3 @ 103, this is with 5 psi off the line and 3 psi the rest of the way. Didn't take much boost to wake this thing up! I have a boost controller on order now so I'm hoping to bump it up to 6 or 7 psi here shortly

Oh, and I can spin the tires now!

I think that if I put it on a dyno I'd find that the power really starts to fall off in the upper 5000's. Right now I'm shifting at 6300 on the 1-2 shift and 6200 on the 2-3 shift, I need to bring that down some. I'm thinking that shifting at maybe shifting at 6100 1-2 and 5900 2-3 would probably be about right. I want to see how it likes more boost though before I mess with the shift points.

I really don't have anything to compare it to. I probably would see some gains from a FAST 90, but for now that's something I don't have money for. Might be something to put on the future mod list.
