I had an ECUTEK Dyno tune on the IX wagon today. The car pulls a lot better with much smoother power delivery and acceleration. Boost builds up quickly and you can feel your back being planted into the seat during acceleration. I have posted the Dyno sheet, note the Torque figure is out by some factor. Final result:
315whp @ 5900RPM
Peak torque @ 4400RPM
Peak boost 24psi @ 4000RPM tapering down to 16psi @ 7500RPM
Mods: SS O2 housing, Custom 3" Turbo back 2 x mufflers & 2 x resonators (no cat), Drop in high flow filter, Walbro drop in fuel pump, GFB Deceptor BOV.
