I want more power from my MY93 WRX. Can it be as simple as replacing the ecu with a later one? I have heard this mentioned somewhere but can't remember where. Also considering the Scoobytunes options from the scoobyshop. Any advice please guys and gals.

How much of a gain do you want? If significant, it's not as simple as this, sorry 
While a straight remap will give gains, it'll be similar to PPP gains on the later my99/00 cars.
An engine lives on air - more you can get in (assuming you can get more fuel in too) the more power you make. But then the fuel system and (ultimately) the internals must be able to cope.
A remap only allows you to optimise any given hardware environment.

You really must start with a filter of some kind, be it panel or induction kit and an exhaust as a minimum..
This will free up some power for a start before you start looking at ecu upgardes..
You can fit 95/96WRX ecus to our cars which will up the power a bit..
For example, our cars come with 230bhp (240ps) as standard, Dan B on here has a full decat/ITG filter and a 95 ecu on his 93WRX and made iirc 272bhp..

Thats what I wanted to know Rob. I've already got a full decat, K+N filter. I've tried the bleed valve route but i wasn't happy so I took that off. I know that the only difference in power on the STi's was the ECU so I wanted to know if it was the same with the WRX. Cheers
