At the moment I've dyno'd my car at 203rwkw with basic mods:
1995 S1
70,500km
Stock ECU
Stock Turbo
FMIC
HKS Pod Filter
2 Stage boost controller
Full 3" Exhaust with 3" Cat
7psi = 186rwkw
12psi = 203rwkw (leaning out at the top)
I was quite suprised by these results because similar model cars with similar mods (some even with PoweFC's) were still doing around the 170-190 power mark on that day.

From here I plan on installing a Malpassi Fuel Regulator (have it already just a matter of fitting/tuning it) and then an Exhaust Cam Gear.
Im hoping this will get me up to around 210rwkw figure.
From their its onto a PowerFC and thats about it for power mods, the rest will be seats, bodykit, wheels and im done (so I hope).
