99 uk turbo with

Full TSL firestorm 3" pipe work
Decat
about to get down pipe

now fitted panel Filter

What im wondering is are ECU's different on wagons?

And what realistically can i Expect if i go down the route of remap new ecu etc

any reccomendations gratefull even if its "save ur money"

 

Wagon ECU is the same as a Saloon for UK cars.
Remap route would be ECUTEK for around £650. This would give you 270-280BHP with full decat and the standard TD04 turbo.
OR
Apexi power FC for about £750 for ECU and mapping.
