Was referred to Nick by a neighbor , so I brought my car in 2 weeks ago for some upgrades and re tune . Picked my car up yesterday and after 2 yrs of head aches dealing with another shop 3 tows from georgina to city and my car ran shitty its like a New car runs like it did prior to all the work. Super happy customer can't stress more this shop is top notch Nick's a wizard highly recommend to all you LS and Lt guys this is your shop hands down...

This shop did poor quality installation and tuning on my car. Had multiple failures which resulted in hundreds in tow charges. The tuning was terrible as it constantly stalled and lacked in power. Every time it went back more excuses on what it was and another bill for the repairs. After realizing they are incompetent, had to take the car elsewhere which cost me thousands to repair their mistakes. Zero rating!

The owner proved to be dishonest and made far too many mistakes in misdiagnosing issues that he caused. Did a cam job on a 1le, and immediately after that, a sound started from the rear... he advised that the qhile axle needed to get swapped out to fix, however, that did nothing but only cost me an extra 7k in COMPELTELY unnecessary repairs... I shouldn't have went back to him, but I stupidly continued to, and he then took me for more of a ride. I made the mistake of getting a clutch installed at his shop, and the weekend that picked it up, it wouldn't go into gear (mind you, it was PERFECT when I dropped it off). He then had to brass to say that my transmission needed a serious rebuild. IF you make the mistake of going to him for any work, MAKE SURE THAT YOU GET ALL PROMISES/DISCUSSIOMS IN E-MAIL, AS HE DIDN'T LIVE UP TO A NUMBER OF PROMISES THAT HE MADE ME - also, ANY work that is done, ASK FOR AN ITEMIZED LIST of what he does, also via e-mail... he, for some reason, doesn't like providing that... don't say that I didn't warn you...

I highly recommend AGP Nick has done Motorwork, and tuning. on my chevy Silverado And my c5 corvette I had issues getting some parts and Nick was very understanding and Patient. So thank you, Nick.

I have been working with AGP to get my car built and set up ready for the dyno shortly. If you want someone who actually helps, explains processes and responds quickly, AGP is the place for you.

I’ve been coming here since the early 2000s when I had an 82 cutlass supreme to have them run it on the dyno. I recently had corsa extreme exhaust installed on my C8 and Nick at AGP did such a good job and the car sounded unbelievable after. Thanks guys!

Late model GM Performance?... In Ontario?... Go to AGP! Enough said. The rest of the reviews will probably say everything else I could say so yea, just call AGP.
