If I could give ZERO stars I would. I had my builder install a Whipple supercharger on my Ford F-150. My builder dropped the truck off to AMP Performance to get dyno tuning and computer tuned. Well no more than 3 weeks and I get lean codes on my sct tuner. Took it back to builder and found truck running lean and destroyed the heads. The Whipple kit is intended to function on stock block and fuel pumps/ injectors. Highly suggest checking this company on google before sending anything to these guys read more

AMP Performance - Auto Repair Near Me - Phoenix, Arizona

I have to give a review of AMP Performance, their customer service is amazing. I had ordered a programmer from their website and unfortunately, I did not order the correct item and the newer version of the item does not cover my application. After I received the programmer and opened the item, I realized I had received the wrong model. I called and told them what had happened and they informed the item I thought I was buying didn't cover my application and that I could return the programmer for a full refund. This is above and beyond what most shops/performance parts stores will do, especially for an opened electronic item. They did not even charge a restocking fee. read more

About a year ago I purchased a TKO600 Coyote swap transmission kit through my builder from AMP Performance in Arizona. Fast forward many months later to the end of the build process and it is time to add fluids and start the car for the first time. From the moment the transmission was filled with the Amsoil from the kit, it leaked constantly. I contacted AMP and they said that it was most likely from the front bearing retainer and that we should remove the transmission from the vehicle and replace the sealant that was used by Tremec. Well...on this car, that's not easy since it has a TCI Torque-Arm rear suspension installed. The labor to remove the exhaust, lower the suspension and remove the transmission is ~4 hours for two people...not including the re-install. Long story boring, this was finally done and my builder got the transmission out of the car. He photographed it, sent me the pictures, cleaned it up and reinstalled everything. My builder noticed in that process that there wasn't any sealant on the bearing retainer...AT ALL! I called AMP to ask why and I talked to Chris. I sent Chris the pictures my builder had sent me and he almost immediately accused us of modifying the transmission and replacing the front bearing retainer with an aftermarket bearing retainer. Chris then handed my call over to Joe who told me his technicians NEVER make mistakes and wouldn't miss something as simple as sealant. I have to ask, are his people robots, or are they human? Humans can and do make mistakes. Now let me back up a moment... We did not set out on this leak fix project to prove anything wrong, but to fix a leak. A couple pictures were taken, and the transmission was sealed up and reinstalled in the vehicle. Lift space at my builder's shop is at a premium, and he can't let things sit around for days. Back to the story... Chris asked for a picture of the back of the bearing retainer after the accusation had been levelled about it being aftermarket and installed by my builder. This was unfortunately something that had not been taken prior to the transmission being reassembled with new sealant in place. Like I said, the leak was the objective, not forensics. My builder told Chris he didn't have that picture last night. This morning, Tom called my builder and apologized for the mistakes (Great! We're making progress!) and the accusation that the retainer was aftermarket. He said the retainer was the correct one, and is part of the hydraulic throwout bearing assembly that AMP installed. Tom told my builder he was really sorry that they had screwed up and would cover the labor for the removal and install to fix the leak they had caused...IF...my builder could furnish a picture of the back of the bearing retainer. Tom knew we didn't have that picture, and it's needless to say they are not covering the labor and now I am paying the price. It is a slap in the face to knowingly require something that the person doesn't have as a condition of reimbursement. I firmly believe that customer service is not how you treat someone when everything goes well and there are no problems; anyone can do that! How you treat a customer when things go wrong is when you can shine and here is where AMP has failed. They have thrown away many years of a good business relationship with my builder and any future business i may have had with them. They have also tarnished their reputation over a few hundred dollars in labor costs over what they admitted was their error. Thanks AMP Performance, I'll let everyone I can know just how great your customer service is. read more

These guys are a bunch of hustlers. If your a younger man or someone who looks like a novice they will hustle you performing a standard job manufacturer says job takes 1-2 hours amp tried quoting me 8 hours job time. There is a reason why nothing in the shop has a price tag on it they give you prices off the top of their head I asked for the price of all the racing seats on display and then sent my father in who is a mechanic and got a 1-200 dollar discount on prices per seat not to mention labor hours to install they doubled the amount of hours it would take to install the seats. They don't realize some young guys know their stuff. I have rebuilt multiple muscle cars just don't have the time to do a couple things myself any more. They lost 5k worth of business by discriminating me by my age. Overall bad people. They sell everything without tax and are overall thieves. read more

After being sold the wrong parts by TWO different employees, they act like it's MY fault for not making sure that they do THEIR jobs for them. I told you the year make and model over and over. The guy even charged me $299 for a flywheel that Summit has for $229. I don't mind paying extra if you give me the right part. But when I have to R&I a tranny TWICE because of their screw up, I'm not a happy guy. If I ran my shop like they run theirs I wouldn't be in business. So good luck if you go there. read more

ARGH having a difficult time with the parts they sourced and returns.

The best auto speed shop here in the valley. AMP has everything you need to work on you Mustang or other American sports cars. The owner Tom and lead mechanic Chris are very knowledgable on just about everything. I've been here many times and have been treated well with quality parts and work. I really recommend AMP! read more

If I could give s negative star rating that's what it would be! AMP are the biggest bunch of fuckin hack mechanics EVER!! I spent over 18K on a build and it was the worst thing I could have done! Thanks for the free drive shaft at least you POS TOM:) That's probably the only good thing I got from those fucks and I hope they go out of businesses. Next time I'll do my homework before I let some scabs touch my shit!!! I'd been better off letting my grandma do the work they did and it still would have turned out better!! FUCK AMP Performance out of AZ;) #Fakemechanics read more

I was looking to purchase a Tremec TKO 600 for my 66 SS396 Chevelle. I contacted AMP Performance and talked with Tom. He was very freinendly and provided me with all the information I needed to make my decision, and with no pressure to buy. I thanked him and told him I needed to think it over. I ended up calling him back a week later to purchase the Tremec. Tom was great through the whole purchase and he even helped answer some questions when my mechanic ran in to a few problems with the install. I would recommed AMP Perrformance if your looking to purchase a Tremec. I also got a great price. Thanks Tom! read more

The people at AMP Performance are top notched. Very helpful and accommodating. They work with a knucklehead like me and see very helpful. I never leave and feel like they are trying to oversell or take advantage of me. That's no small task cause I'm off Irish decent and feel like that most time. Give them a try. read more

I came here a few years ago to buy a clutch and i specifically asked the guy if everything i needed came included and he said yes then when i had my car at the shop they told me the pilot bearing was missing so i tried to call back to let them know and they put the blame on the company who makes the clutch while i do agree that some of the blame is on that company the guy at AMP did not make sure he was right so when i threatened to report them to the BBB he kindly responded by saying do you know who the KKK is? read more
