I know this is a stupid question but i'm new to the VW scene so i'm not completely aware of all the tuners around Melbourne.

Are there any tuners that protect the new car warranty with power upgrades. I know MRT do but they don't touch 2011 Polo GTi .

Looking to do a ECU Tune and Exhaust. Probably Strut and sway bars to.

Any help would be great as i'm already getting hit with the tuning bug but i would prefer not to void my warranty.
