Matt and the team rebuilt my LS1 and transmission back to factory fresh condition. I was kept up to date the whole way through the project with photos included. I can't praise enough the quality of work and professionalism of the whole team. They turned an old well used 400,000 km drive train into brand new.

Hands down the best service I have had. Only the best quality parts used and the service is second to none!!! Couldn’t be happier. Iv had my engine basically rebuilt with cam upgrades and everything else, new diff installed and now airbags supplied and fitted. Won’t take my buisness anywhere

I had my Cv8Z tuned by Matt at PSI and I must say I don’t think I’ve been to a tuner that has explained the things he’s doing and done on my car it was tuned before by another company but Matt cleaned it up took fuel out and extracted more power and was still a safe tune so if your thinking on how and where to go I can 100% recommend PSI for all your needs I’ll definitely be back to him with any other jobs

I recently had my 02 Monaro worked on by PSI performance and the experience was outstanding from start to finish. The communication was excellent, they kept me updated throughout the entire process and were always clear about the next steps. I appreciated the regular progress updates and the transparency at every stage. The handover was smooth, with everything explained in detail. The team truly cares about both the car and the customer. Highly recommend their services to anyone looking for top-notch performance work!

The team at PSI Performance are top blokes. Had them fit front Brembos and she's never stopped better. Will be taking my Caprice here again for any work I'll have done.
