Can’t speak highly enough of Stuart’s workmanship and customer service. He replaced the turbo on our diesel Ford Transit at short notice and was so straight forward and helpful. Very grateful and highly recommend his services.

Amazing experience with Stuart from Skillen Industries! It’s incredibly refreshing these days to find someone who actually communicates promptly, arrives on time, doesn’t let you down, does a fantastic job….AND within budget! All with a friendly smile and a really nice bloke. Cannot recommend him highly enough!
Robert Denko
I was amazed to find out Skillen Industries provides tunes for Berrima Diesel! I’ve been putting off the 3.5hr drive from Newcastle for months but Stu from skillen industries came to my door step and completed a remote tune on my 2021 D-Max.
The extra pickup and smoothness of the vehicle is 100% worth it !!
