Bought it 4 months ago, and now it has these following improvements:

-HKS EVC boostcontroller
-HKS airfilter
-3" SS Catback-exhaust
-Apexi turbotimer

-Tein S-techs
-Whiteline rear anti-rollbar
-16" Oz Superleggera rims

and then the pics...

so you are changing to a piggy back ecu?

if you are going to keep the standard ecu then taking the fuel cut off the ecu is a very very bad idea.

the standard st205 unit is only programed upto 1.2 - 1.4 bar fueling with a ct20 as the turbo, if you crank it up more boost then irrelevant of the boost coming in the ecu will only fuel the maps it is capable of, i.e. 1.2-1.4 bar max, and that will inevitably melt your engine, fcd on an st205 without a proper aftermarket ecu is a big mistake
