Ok so I have my car booked in for a retune on the 12th of October at ASG in Perth. I am getting a turbo back exhaust fitted and an open source Verso tune on my 08 Sti Wagon (Auto).
After contacting the tuners and asking them their opinions etc they have informed me that in their opinion after market TMIC and intake are not really worth doing and they have found no real gains from these. They suggested looking at replacing the turbo and/or headers.
I dont know if I totally agree with what they have told me but would like your opinion on possible turbo/header upgrades. Ultimately I would like to aim for around 240kw atw.
I will probably still do the TMIC but not entirely sure where to go with this either? I have considered a Process West like Rome however there is the issue of engine covers etc not fitting, or I could just go with an AVO?
