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 recently had a head and cam package on my 05 clubby and My experience at psi Performance was probably the best I've ever seen. Such nice and easy people to deal with. answered every single question I had always gave me regularly updates on my vehicle. If you're looking to get work done to you're car PSI PERFORMANCE is the place to be Definitely will be coming back for more Thank you so much for the great experience keep it up!!
Could not be happier. These guys know their stuff and will look after you through the whole process. Answering all my questions and going above and beyond to deliver a really amazing result. Thanks Matt and Dale for your work 🙏🏻
This was the most positive experience I have ever had with a mechanic PSI PERFORMANCE especially Matt was so helpful, honest and full of knowledge my engine was replaced and I'm still in love with my WM CAPRICE the photos that were sent to me step by step were an awesome bonus and communication was sensational I would highly recommend them ...A +++++ THANKS MATT
Been looking around for a right place to get my mods done.. PSI Pakenham is THE place to go to.. from dyno tuning to basic car services they provide everything with quality and reliability in one go .. highly recommend them.. services are top notch and got great deals .. can’t wait for more !! 🔥🔥🔥🔥
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.
