The unichip? Do you mean Utec? What better engine management will you get elseware for the price and availability for assistance (tons of people running it; starter maps (wrxhackers); etc)??? I don't feel that there are many companies that out-do txs in the WRX circle. However, I do agree that Perrin makes nice stuff!trenton said:Turbo XS doesn't really make me go crazy. They have a cool TMIC. The Unichip would probably not be my first choice of ECU, but it's cool nonetheless. Nothing of theirs really impresses me i guess. I can get it all elsewhere.
