GM Motorsport 23 Reserve Road, Melton, Victoria 3337

"Have been dealing with GM Motor Sport for nearly 20 years and many LS vehicles and lately 2 Ford Rangers. All vehicles have met the performance results promised. Have nothing but a high regard and respect for the team. Have always been welcomed and helped to get the best results for these vehicles."

"Great experience when getting my full exhaust and tune done, good communication and customer service would definitely recommend."

"Could not recommend these clowns any less ,nothing but attitude and big ego's.... Better off saving your hard earned and going somewhere else, no sour grapes here....just letting all Ls1 owners know, don't bother with these trash bags This is a reply to the owner There is no need to go into detail, your company was given the opportunity to do the work that was paid for... Unfortunately it wasn't done properly as I'm now learning of previous people who have been there for work... I will now have to pay another company for the job that was meant to be done by g.m I will not recommend anyone go there.."

"It started with an online enquiry I made wanting a price on a full exhaust, intake and tune. Instead of getting back to me by email, I received a phone call from Danny there at GMM. I explained what I wanted, he then gave me many options and asked me if I would be making additional modifications in the future. He took all I said into consideration and suggested what I should go for, given the mods I would be making next time. So I booked it in. When I got my car back after the work was completed, I was so impressed. They had transformed my WN Caprice in the way it drove, how it sounded and how it performed. From start to finish the guys at GM Motorsport were first class in every way. Phonsy's tuning skills can't be topped, and Danny's knowledge and customer service is unrivalled. My car is a completely different beast now. I can't recommend GM Motorsport enough. If you're looking at getting some more performance out of your car, give GM Motorsport all call asap! You won't regret it."

"I chose to take my car here for a tune on my v8 commodore as i had purchased a camshaft from their retail store. they should have solid experience with their own product. When i recieved the vehicle back they had forgotten a number of things and had not followed my instructions on how i wanted my tune, Also wouldnt idle as it should. Upon further investigation i had removed the heads and found that the engine was running DANGEROUSLY LEAN!! (pictures below) luckily i had found this before it was too late and my engine went kaboom! I had then approached GM Motorsport and attempted to have the vehicle rectified on all occasions they had other WORKING and tested componments to blame and have directly refused to assist in completing the job they were engaged for in the first place, I had then spoken to a few other tuning places and nobody wants to tune my vehicle after GM motorsport had drilled a hole in my throttle body (poor tuning for idle) now i have to pay for a throttle body and a re tune. I strongly do not recommend this workshop as their quality of workmanship is poor and over priced and the customer service is terrible once they have your money"
