to go from 215 bhp to 240 bhp on a classic with just a centre decat, a panel filter and a backbox change?

 

with the help of a remap im sure it could be done

 

no remap just those mods, i don't think it is possible

 

Yes its possible, depends on the ecu, you dont mention what car? ask Rich D, his car is a full decat and filter, pulled 250bhp on an AE800 ecu MY99.

Entirely possible if the car you start with has better than factory figures out of the box -which many Imprezas have.
I've seen totally stock cars make 230 on the rollers, but lets face it - rollers ain't accurate

 

mine has decat, back box, panel filter, but also with newage intercooler and a remap. 97 classic turbo running 260hp. alan jeffreys is your man for the job!

 

sorry to jump on this thread but i was told 97/98 ecus were unmappable,do you have a standard ecu or did you change it?

 

Would love to say but rifleman is your guy to ask as I bought it off him but can't remember which! (my first scooby so still learning )

Sorry!!!
