Im not sure if it would have been better with a good launch though.

Whats up with the Dyno curves? Seriously wierd horsepower output! It goes up and way down and back up. You need to have it tuned again. I think your Turbo is trying to draw boobies on the dyno graph!

Here is my Dyno with about same mods: evo stage 2, V-flow, DV, Ruf exhaust. This was done by Dyno Dynamic and with no fans point to intercooler. So the number is really low. Your number is about right from 2 wheels dyno, But just compare the shape of the graph with mine, EVO site graph and yours. Your HP and TQ drop a lot after 5K??

Yeah, I just looked at mine and I do not have the camel-back hump (boobie curve as referred to earlier) in the HP and mine does not die st 5K rpm...think maybe some fine tuning to the program is in order.

I regularly see 1.2 bar and occasionally 1.3 bar on my boost gauge . The car seems really fast.
BTW, the dyno says "flywheel hp" but i was told it should say "wheel hp"

There is defintely SOMETHING happeing at 4800 RPM. Either overboost, or maybe the computer is falling into limp mode (not enough cooling on the dyno)?
The shape of my graph looks pretty similar to EVO's.

Took the straight pipes off, steady .9-1.0 sometimes and it felt 100x different!!
