Hi,

I have worked and learnt about Subarus for a couple of years now, so I went a bought my first proper turbo car. It is a 1997 Liberty converted with a V3 STI engine. The AFR is running extremely rich under WOT (around 9.5:1). I know an ECU and tune is the best way to fix it, but I need to save up a while until that can happen. I was wondering an easier and safe way to fix this. I am not looking at making more power, just for it to run more efficient.

Mods from previous owner: td05-20g turbo, FMIC, electronic boost controller, wideband O2, TBE, yellow injectors (not sure the cc exactly). It is on the V3 STI ecu at the moment.

Thanks for the help!
