Its not a bad kit however its 400...to the engine!
I finally got my car tuned right at Ptuning and with the following mods, most of the kit from Z1, i love how it drives.
For power I have NST pullies, Ported Intake Mani, Stillen Headers, Berk HFCs, Motordyne Cat Back Exhaust, Stillen Gen III Cold Air Intake. Driveline is a Spec Stage 2+ Clutch w/Steel flywheel and a Quaife Diff with 4.08 Gears.
The date is off on the sheet but this was done yesterday at Ptuning. There is no wonky calibration factor or any of that stuff.
