Hi all. Just been on the phone to Powerstaion, they said you can't re-map impreza's pre-99. i have a 1994 wrx and wanted to make it faster with a re-map.. any one got any idea's or done it.. or would upgrading the intercooler do the job?

A new pre programmed chip is what you'll need.

uping boost etc for increased power.

has anyone used the ECU upgrade from Horsham Developments? any good if so??

 

Nope, but I have spoken with the guy and he seems to have fair idea of whats going on in the ECU. Although IIRC he was trying to lean them out quite a bit. Probably using his Nissan tuning experience, which may not be quite the same for a Subaru AFR.
