i will get another dyno after i have my engine rebuilt and throw the power fc on and bump up the boost to 14-15psi!! hoping to get 230 4wkw's, atleast!!

26/4/07

had the rebuild done. made 175rwkw's on 9psi. dunno where the power went. nore the boost

currently running 239.8rwkw's on 14psi. (about 321rwhp)

new mods:

Trust pods

Haltech e11v2

Cam Gears, still set at zero at the moment.

they believe i have steel wheel turbos on but not too keen to run too much boost until i am certain for my self that they are steel wheeled, then if they are im gonna throw it up to 18-19psi.
