2014 Volkswagen Golf GTI - Performance Tune

It was great to discover how experienced Lars is in ECU tuning. He had a very no-nonsense, and very professional approach to getting the best out of my Mk7 Golf GTI without going over the top.

The results were amazing!... he turned my already great car into something much more top shelf but without the price tag. Highly recommended.

I can see and feel how much power it has gained. It's like hard to control the speed LOL.

Jose Mercado – Massey, Auckland

2006 LS460L - Performance Tune

My car was tuned by AutoUpgrades, and I am pleased with their tune. My car definitely gained more power and torque. Lars managed to do a pops and bangs tuning, and it changed the car's personality dramatically. It is faster and more aggressive than before.

I love his tuning, and it is why I am his repeating customer. Thank you so much for tuning my car. I highly recommend AutoUpgrades to anyone who is thinking of tuning their vehicle.
