Hi Guys,

My first post so hopefully in the right area.

My Question is, I have just bought a new 200 Series GXL 4.7 Petrol and want to know who specialises in making these more powerful with better economy. Normally done by remapping ECU.

I have a Holden 6lt V8 which has been tuned and increased both power and torque and improved fuel economy.

Who in QLD is the best person/workshop to speak to.

Thanks
