Hi guys,

Ive done a few mods to my VX ecotec including pacemaker extractors 2 1/2 inch, lukey sports cat, 2 1/2 inch lukey exhaust, bigger throttle body, wide mouth ss induction cold air intake and 10mm top gun ignition leads.

Would I benefit from a re-tune/flash tune or will my stock ECU adjust itself to my mods?

And what sort of power increase can I expect from getting an aftermarket reprogramable ECU?
