Hey guys, Martin from XAT. Here are some numbers on the stage II kit. I am flat out impressed with the power on this and I have dynoed and tuned hundreds of cars and setups. PJ at Boost Designs did a incredible job matching their new spec turbo for their kit to tha KA24. The dyno chart does not lie.. 8 psi by 3300 rpm !!! 240 foot pounds at 3300 rpm... Recirculated wastegate. The clutch slipped once because it is fresh and not broken in yet .. but it was for a 100 rpm section (loop you see) This power was on 12.1 psi on a E-01 and timing was conservative.. I was running about 18 deg timing at peak boost and a pretty fat fuel curve. This is incredible power that stays and makes the car move all the way 6700 rpm. E-Manage does a decent job but we will be doing rom tunes in the future... and PJ will be offering this with his kits pretuned through Scott (Enthalpy).Will have some stage 1 low boost runs tomorow.
