APR

I’ve had nothing but good luck with the APR software used in the past. My sister’s VW GTI Mark V series was a decently fast car stock, but after we added (my present to her one year), the stage 1 APR software to her stock ECU… OMG! That was like day and night! The increase in torque was amazing, night and day, pulled super hard from 3K to 5K. Pulled great for just a little 2.0 liter 4 cylinder. Same or slightly better gas mileage as well, and less need to down shift from 6^th to 5^th to pass … or if you really wanna go, drop it to 3^rd and floor it! This was the best $ 600 performance upgrade you can get, and switchable too back to stock… the dealer never knew! APR has lots of Audi products as well as VW. Best money I ever spent on sis’s car. Now, to mod my BMW V8 is gonna be a lot more! Best bang for the buck, and still running great after 88K miles!
The only thing that might make things better is having more authorized installation dealers. We drove all the way to Davis Ca, about 70 miles to get the APR software installed. If I drove an Audi or VW, APR is the best software upgrade to do. No hardware involved, modifications by laptop! Now, if they could only fix those VW diesels this easy!

These guys rock! I ordered a part for my audi and decided against using it.
I was well past my 30 day return period, but they went ahead and refunded it anyway.
Thanks APR

I’ve been doing business with APR for some time now and I can say that this company stands behind their products and most importantly their customer service.
Highly recommend!

Not only are their products amazing, they are extremely helpful. I can always call them with any questions I have, and they are happy to help out. Very friendly and professional. Will not hesitate to do business with them again.

APR DOESN’T STAND BEHIND THEIR PRODUCTS
Had an APR chip in my Audi for about 4 years. Started having intermittent engine shutoff problems and finally the car just wouldn’t start. Took it to a mechanic who in the end found that the ecu was bad. Sent the ecu to APR to check if their chip failed causing the ecu to go bad. It indeed was their chip that went bad but they wouldn’t reimburse me for my mechanics fee. Told me I should’ve called them right away when I was having problems with my car…

I have been here several times and this is the only place I would take my Audi to be tuned… ever!
I have known this company since it’s infancy in Auburn. In fact, I remember seeing the owner’s A4 shooting around town and wondering about his car many years ago. They have grown tremendously since then and have a wonderful reputation as a tuner and developer.
Everyone on staff is very professional and knowledgeable. I have called on several occasions and they always have the answers. The facilities are state of the art with the latest and greatest equipment, software, and staff.
The annual BBQ’s are a must attend… they have a raffle where they give away a 5K Stage III Turbo kit every year, recap the race teams year, display the cars and new products, provide BBQ and tours of the facility. Also, they offer price brakes on products and free installation.

Well APR does a a wonderful reputation I have to say that as a consumer you should use caution when accessing their dealer list. I used there dealer list to to order $ 4K of their product from one of their dealers. After three months of waiting it came out that they had put this dealer on credit hold prior to my order. APR has told me that my transaction was between myself and their dealer and that they would not get involved.
It is my feeling that if you have authorized dealers and you place them on credit hold then you should be compelled to remove them from your dealer list. This would protect the consumer from ordering product that could not be shipped. APR has since removed this dealer from their site and I have not received my parts or a refund.
It makes me sad that a company like APR would just leave a customer high and dry.
