Had my Mk4 golf R32 tuned a couple of weeks ago, more power, smoother power delivery and seems to be better on fuel, couldn’t be happier.

Royce Evans

Have had my Ford Ranger tuned by Alt Tune thanks to Mag & Turbo Porirua – and what a difference it’s makes. Low down torque is super punchy and definitely worth it in my opinion!

Josh Merritt

AltTune goes above and beyond. Have been using their service for a couple years now and never had any problems. Great price and high customer service.

Will continue to use and recommend.

Luke Adams
