Can anybody tell me if your cars ecu(the whole box)is replaced when you get the PPP? Or do they just open the exsisting box and change one of the "chips".Any info on this will be great.My wrx PPP makes 233hp and 224lbf-ft using 97ul fuel , how does this compare to your figures in the UK.
Thanks
Gerrit

 

The PPP ECU is a replacement, take out one, fit the other, go and play For best results add an exhaust system and air filter.

 

mine has 243Bhp with pro drive ecu and prodrive B B plus blitz cone filter TSL downpipe forge D V and its going to get better ??? cheers alan
