3 to 6 psi depending if flat or a slight incline , 250 to 300 deg on the pyro , and 2200 at 100kph

flat ground 3-5psi, 270-310 on the pyro, 2500 ish at 110.

how are you running 250* winmag? how much fuel you using?

Thats how, 3" pipe and boost controler, that prevents waste gate creap. ie waste gate doesn't move until desired boost is reached making turbo spool up quicker and run more efficient. 11.7ltr/100km 47 deg C ambient Cober Pede to Port Augusta. Pump has run out of ajustment, puting bigger pump and injectors soon.

300Winmag what boost controller are you using? and is the a big differance in spool up time?

Thanks GunGU

The boost controler is just a $20 E-bay speical, it is actually a ajustable pnuematic pressure relief valve. Makes a big difference in spool up and stops surging just before waste gate is fully open. My power curve on the dyno just ramps up in a nice curve to the culminating point, no nasty spikes or dips.
