Volkswagen Accessport V3 Golf R (Mk7) 2015-2018 USDM is rated 4.9 out of 5 by 7 .

Rated 5 out of 5 by RGolf from Been using the AP for the past few weeks Worked my way up the Stg 1 maps one by one to the Stg 1 93 High Boost map. It makes a big difference compared to stock. Faster response and stronger pulls. All driving modes are better. If you are concerned about impact to MPG, I tested driving conservatively and gas mileage is unchanged from stock as near as I can tell. If you push it, it seems to use slightly more but this is hard to quantify. I use the gauges all the time as well as the code checking(none have surfaced so far) and also ran the performance timers as well. Everything works as advertised and overall I am very satisfied. I would love to see some updates on the Stg 1 maps to see if more power/torque can be squeezed out. After initial flash(~20mins), subsequent ones load very fast (couple minutes).

Rated 5 out of 5 by Ethan from A Necessity for the Golf R I've wanted this since i got my Golf R. I felt the car was always lacking a little bit of power and this is exactly the boost that it needed. In a few years I'd love to go stage 2 and this is amazing that i can flash it right from home. After downloading stage 1 I drove around a few blocks in sport mode and could feel the power difference when I tapped the gas. Not to mention that all of the gauges are very cool and I love looking at them. My only real complaint so far is that the 0-60 timer is not accurate at all, i did a launch and it timed 8.5 seconds which was definitely wrong. It felt faster than all my stock launches and I'd guess it was low 4's. Not a huge deal, but just a little annoying. Overall, great product, and a must-buy for any R owner. I hope to go stage 2 with COBB in the future.

Rated 5 out of 5 by bcowan64 from Very pleased I bought this for my 2016 R manual. I am running the stage 1 93 octane high boost map. Installation was very simple, and the added power is immediately apparent. This is my 4th Cobb AP. I had one with a 2004 Forester XT, a 2008 WRX, a 2012 STI, and now the Golf R. Nothing negative to report on any of those platforms. Cobb does excellent work.

I flashed my car with the 91 High Boost once finished i used the cobb module as a boost gauge (i was not planning on keeping the module plugged in, but it does look very nice) Stock boost (from the Car dash is 32psi ((roughly))) to get the actual boost you have to subtract 14.7 so that gives you roughly around 15 psi of boost THIS IS STOCK BOOST with the tune (and using the cobb boost controller) i peaked at 21.3 psi of boost. that's a decent 6 PSI the throttle response was very nice and you can some difference in pull. Over all, I would look into getting your car ready for a stage 2 tune, but to open the car up more and have it more respectful this is a good product to purchase

Rated 5 out of 5 by 206 from Awesome Versatility! To be clear- I have yet to fully explore all of the functions of the AP. There are so many metrics you can monitor and of course different OTC tune maps and custom tuning options to check out that I've really only scratched the surface. BUT I've really enjoying playing with it thus far. Stage 1 high boost is a nice pick-me-up from stock and has gotten me excited to do more.

Rated 5 out of 5 by Shawn from Love it I love this! I am only on a stage 1 93 tune But there is definitely a noticeable difference. I can’t wait to bump it up to stage 2 here shortly. Thanks Cobb for consistently making great products
