I bought a Camaro from a private seller about a year ago. Said this shop did all the work installing the ported heads, cam, bigger and smaller pulleys, dsx fuel pump, etc. Took it to another shop to see how much it was pushing because they had a hub dyno. The car ran really lean past 4.5K RPMs due to the dsx not working anymore. Decided to get a fuel pump with a return line.

When the shop removed the supercharger the bolts were stripped going into the head, they used a bigger bolt to tighten the supercharger down, reused gaskets, didn't even have the snout ported to the 103 mm, just used an adaptor that connects a 103 mm throttle body to the stock 90 mm. Over all I didn't get work done here at this shop they sure like hiding mistakes they caused pretty well without even telling the customer.

Such an amazing business. Fair and honest pricing and service. Customer service was beyond what I would expect, with great communication. I would absolutely recommend AV Tuning to anyone looking for a great tune. Their Mainline Dyno and the tune Anthony provided was awesome.

Best experience with a shop ever! I can't recommend them enough. Very professional and super helpful. Constantly called me with updates and did an amazing job on my car. Not matter what your horsepower goal is they will get you there. My car runs great and they do qualify work and use quality parts and don't cut corners.

The owner is a very honest straightforward person.the cost of everything was explained in detail.no surprises! The job was done on time. They kept me posted of the process and progress. You can email them anytime about any concerns and you will get a reply even after you have paid. I knew I was paying a premium price and I expected a premium job and I got it.100% fully satisfied! I'm enjoying my supercharger on my 2015 mustang gt. #S550. FIRECRACKER

If I could leave 30+ 5 star reviews I would. Long story short, I purchased a 14 C7 Stingray with a P1SC Procharger setup and aftermarket oil catch can. Didn't do the due diligence myself of getting it checked out before buying. Originally went to AV for a tune but upon their first inspection, they found pages in pages of issues with the vehicle. After three separate visits, all of which new issues came up due to shotty installation from the previous owner, the car is finally perfect. AV spent so much of their time helping me, and fitting me in even though they were slammed. Anthony was who I dealt with personally, and you will not find a more up-front and honest individual in this business. He gave me confidence and treated me more than fair. The whole team was amazing and I could not recommend a better performance shop, period. Thank you guys again!

This is a delayed review due to wanting to give a thorough review. I first took my Challenger in for an aftermarket tune. Anthony is very knowledgeable and thoroughly explained the procedure. I was definitely pleased with the results. Last month, I took the car back again for headers and exhaust. Again, outstanding job, very pleased with the results. You get what you pay for, and it was definitely well worth it. Very professional but also very much in demand.

I drove from Tennessee to have my Ford Focus ST pro-tuned and I am amazed by the work they did and the customer service. I highly recommend the pre check inspection they offer. I had a catch can that was defective from the factory and caused the engine to smoke on full throttle acceleration. They quickly found the problem and fixed it. Then they tuned the car and it was a night and day difference between an E-tune.

Then after I returned home I was having problems with my launch control and they were able to tell me what to do to fix it. They have kept in touch and answered my questions even 3 months after my service. Great people and a great shop.
