B5 S4 BEST BOOST GAUGE CODE

I was glad to see APR revised the code when it was determined that it was suffering from poor timing in the mid-rpm band. It was reliable and provided a substantial boost in power. I never had any problems with it my turbos and TBB never failed, though I replaced my DV’s as a precautionary measure. I have been very pleased with the performance of the APR chip and the support they have shown for their product. Passing on a two-lane road is one place when the extra power comes in very handy. I wanted the extra power for those times when accelerating in a hurry was very important. I did not purchase the chip so that I could drive the car at higher speeds or in a more aggressive manner. I had attended such a school a couple of year’s prior, but I do not support this position. Others will argue that you should attend a driving school to improve your skills at handling the car prior to adding so much horsepower. Adding 50-60hp is a real noticeable change. Installing the chip is a very easy process and takes about 10 minutes when you know what you are doing. My Audi S4 at the APR facility in Alabama Only the addition of my Coilover suspension produced such tangible improvements in performance. Their price was comparable to other tuners and the results of performance tests led me to conclude that there is a negligible measurable difference in the performance of the top tier tuner’s chips.Īdding a chip to the modifications I have done to my car was one of the best improvements I have experienced. APR has had a great reputation and one visit to their web site demonstrates that they are a company that is working on new and innovative ideas. I thought about their reputation of product design, customer service, price and performance. Reason:Ĭhoosing a tuner that I felt comfortable with. The following is a discussion of the modification I did to the cars ECU chip.
