Thanks for the great feedback
Looks like the general opinion is ECU tune offers the biggest difference which means the best bang for your buck mod.
Next is the Mid pipe and there after the FMIC and other stuff like intake.
Thank you Ian for your suggestion regarding the FMIC reducing the possibility of timing being pulled back when on a hot day. I can noticed timing being pulled back even now (all stock) when the temp gets a bit more humid. Don't want to image when it will be like during a hot summer day
