i just bought myself an MY04 rex and was looking at getting some simple mods for it..
Realisticly i wanted to get an Turbo Bach Exhaust.
By im being told that i need to get an ECU re-tune at the same time to manage the variable cams and also get some new maps installed.
Any one got some ideas?
And also if any one is aware of an ECUtek re-tune or an AVO re-tune?
