the only engine/powertrain related mods i have on are xForce turbo back exhaust (3in) and AEM airbox.

i have some questions about the manifold pressure chart. after the tune, the reading is around 244kpa, or 35.4psi. to calculate boost pressure, i need to subtract 1 atmospheric pressure aka 14.7psi from it. 35.4 - 14.7 = 20.7psi. is 20.7psi my actual boost pressure? or have i made a mistake in the calculations? that seems kinda high for a bone stock engine and turbo. if my calculation isn't wrong, then doesn't 186kW(250hp)/378nm(280lb`ft) on the wheels seem low for this level of boost?

 

Those numbers are high for those two mods and no tune. Need an evo x turbo for that

 

the numbers are after the tune though. you think the dyno sheet number could be inacurate?

 

I'm not sure about your calculations for the manifold pressure but the HP and Torque numbers don't seem impossible(maybe a little generous) with a tune... What method are you using to up the boost pressure? i.e. boost pill or aftermarket boost controller or some other method I'm unfamiliar with?

 

Well, that dyno sheet is using 1.76 correction, so yes, and it's a mainline.

Curves look good though.
