Could anyone from around the SW London/Surrey region help me work out, whats wrong with my 93WRX???

I think there is a boost problem, as it hesitates and sounds like it is 'choking'

Am i driving it wrong, or is there a mechanical issue?

No I havent replaced the ECU

It actually happens while blast off/throttling down the accelerator.

It was supposed to be fixed, but it seems to have come back.

Which is why i think its the way I drive...

Would appreciate someone taking me for a blast in theirs, and then the same in mine...................

93WRX ecus **** up. Its a known fact. You need to get a post 95 one and fit that (they're called Z4 ecu's). Its something to do with crap programming or summit.

Before I replaced mine the boost would got to 0.5bar sometimes, booooo, and 0.8bar other times Now it goes to 0.9bar all the time

how much you looking at for this new ecu off a 95, coz my mates k plate wrx is just the same. floor it, ok in first, sometimes ok thereon sometimes crap and stuttery as the revs pick up about 4k onwards. ???
