Guys, after some of your knowledge.

My '95 STI wagon was 260ps as standard on the TD05 turbo. I am after more power! I have a set of 550cc injectors and a V3/V4 intercooler just purchased both ready to be fitted. I cant find a cheap Simtec or Apexi ecu to replace the original. Could i have a polar chip made to suit?

The car is running a Walbro fuel pump and a full turbo back catless 3 inch system.

 

the polar chips are based on 380cc otherwise it would be fine you would see roughly around the 300 mark with you mods best option id say would be to go for a esl chip which is very popular

 

Cheers, just found a link to them.
