Chipwerke piggyback chip tuning system for Audi S4 & S5 3.0L TFSI (2009-2016) - get up to 33% more HP & TQ

Very impressive! My wife and I felt a significant difference in power, will be testing it at the drag strip soon, with/without chip and then on 104 octane on setting 6.The oil in the car currently has lost 40 percent of it's life via oil analysis, and yet I am seeing 3-4 mpg increase! Will conduct drag results without junk dealer oil, will be using amsoil euro blend with nmf friction modifier that I use in all 4 of my cars with exellent results.Side notes the chip was already turned to 6, I turned it to the recommended 5 for 93 octane, also the directions didn't say which harness goes on which side of the engine I later find out it doesnt matter.

The seller is GREAT! This went on a 2013, Audi A4. This original unit did NOT work at all. It essentially deactivated my turbo making the car slower than stock. It also activated the check engine light no matter what the settings were. I contacted them and they sent me return postage and I sent it back for testing. They tested it the day they received it and got it back in the mail on the same day too! They said there was a communication program error (or something like that) and redid the program. I have it on my car now and it seams to make a noticeable difference. I haven't had the CEL reappear. The reason for four stars instead of five are as follows:1. Even though the installation is super simple, the instructions could be better (seems like it went through babel fish).2. The website seems to give the same results of power/torque/mileage increase no matter what car you choose and this makes the website seem sketchy.3. Related to #2, there are no dynamometer tests (maybe one?) of the units, again making the website seem sketch.4. There is no description of what exactly each module does to each car. i.e. for you car, each click on the dial increases the boost x psi resulting in x hp/f-lbs/mpg increase.If they provided this type of information and guaranteed these numbers if tested on a dyno, then I don't see how they could keep these things on the shelf. They could do something like, if you submit your dyno results for a model and year they don't already have results for, they credit you $75. Limits their downside and gives INCREDIBLE marketing.

Works as promised and advertised, throttle response is quicker, and on the 3.0"t" supercharged engine, the boost isn't by-passed after 5000rpm like the OEM tune does. Full boost at WOT all the way to redline. Installation was a quick 5 minutes on each manifold sensor, great little box.

Best bang for the buck mod. Super easy to install and remove for dealer service.

Great bang for the buck. Quick, easy install in my 2011 Audi S4. Very noticeable boost in performance. Comfort mode still feels stock, but when in dynamic mode, it's much more aggressive and responsive than the stock dynamic mode.Quick response from the seller confirming vehicle info and fast shipping. Excellent product!!! Thanks!!!

Instructions leave somewhat to be desired. This is a no frills solution to immediate power increase, in my case for a 2014 Audi S5. Not sure the power delivery is as smooth or as linear as I'd like, but you feel it where it counts - in the seat of your pants!

The Chip works amazing, their customer service is great. They will get in contact with you after the order to make sure that they get you out the correct product.As for the chip, for sure the biggest bang for your buck. easy install and you can totally feel the difference.

It hooked up easily. I love tried it for a couple weeks and so far it’s difficult to tell that their is even a tune.

So so easy to connect.The pro version does not come with the aluminum case but was set to 5:1.The power/torque is definitely noticeable and fun for daily driving:It does have some glitches at WOT ( cuts power/boost) in the high RPM when really trouncing on it.
