Chris Quartermaine

Sheldon remapped my 2006 Toyota hilux in March 2020 as it was severely lacking power and struggled to pull a 2t feed trailer up a hill. First he ran diagnostics on the motor before remapping.
After the remap, the increase in power was significant and now my ute pulls the trailer up the same hill with ease. He is now booked in to remap my tractors. Very happy with his service and professionalism.

Had my cruiser booked into Sheldon for a EGR solution and remap and to say I’m happy with it would be an understatement more power and better fuel economy. Also found and repaired an issue with a valve. would definitely recommend refined diesel solutions to anyone that is thinking about getting there ag gear or 4×4 tuned.
