Hey guys.. I drive a MY09 SV6 non sidi and was wondering if anyone has had theirs tuned.. what mods and power did it make after a custom tune and who did it? even differences in sidi's that have been tuned. I want to change headders and cats and get better bottom end torque. Not sure it its true but i heard they have a limiter for torque up to 3k revs? and can it be removed? some places have been popping up as now tuning the previous untunable sv6's.. just where in melbourne? p.s. Im on p plates so dont say go get a V8 and give me **** for trying to get some more power out of a v6..
