Marcel here from Johannesburg, South Africa, recently upgraded from a Golf MK1 (yes, these were recently discontinued in SA after 26 years, Still have my die hard 2004 Model with 150K miles on the clock) to a WRB MY10 WRX Sedan.
We have the Australian Spec Scoobs here and this would be a WRX with around 275 FlyHP (Stock), this is around 200HP WHP at one of the local dynos . I have recently fitted a Subaru approved Bosal exhaust and had OSS software map done. This was done more for safety than power as our fuel sucks. The map is for 95 Unleaded pump fuel.
Havent had it on the rollers yet but would expect gains of around 20%.
Lekker and good to be here !
