i would like to have a turbo kit for my 1.6 and i found that topicUni chips are pretty popular in Singapore. Nearly did on mine, but opted for OBDII tuning instead. Has a more natural feel, smoother progression up the powerband.
Unichips work well on turbos though - consider a mild boost kit (up to 1 bar). Can't really go further as the comp ratio is pretty high already -10.5 to 1. 20% gains on hp is realistic.
