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.

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 !!
