Dyno Gain (% TQ) Peak +31%, Max +37% at 2500 RPM

*Results may vary. Power as tested on 2016 GTI Manual using these identical calibrations. Generally speaking, the 91 octane calibration has a richer fuel curve and a less aggressive ignition advance map to help compensate for 91 octane fuel and/or less than ideal atmospheric conditions. The map designed for 93 octane is the most aggressive.

Rated 4 out of 5 by from Excellent Customer Service I bought the AP from RallySport Last week. Installation was simple and quick! The features of the V3 are amazing! Unfortunately I had an issue with my intake manifold so I had to remove the unit to take the car in for service. However in troubleshooting the issue prior to a shop visit Grant from Cobb CR was very helpful. He responded quickly and then asked for an update once I found out what was causing the issue! I really appreciated the quick response from the Cobb team and they for sure made me feel like they genuinely cared that I got the car back in working order! I absolutely recommend a purchase from them and will be going back for parts in the future!

Rated 5 out of 5 by from Great mod I bought this about 2 years ago and I still use it. It’s amazing for showing you all the data you wanna see on your dash & it’s pretty accurate! You can swap tunes on the fly as well. There’s been rumors that the stage 1 & stage 1 plus tune ruins the clutch in manual cars fast, I will say it’s false. I was on a stage 1+ 93 octane tune for at least a year. Now, stage 2 might do more harm if you’re still on a stock clutch. Although in my case, I drove it daily and hard from time to time. It does not ruin your clutch, BUT can increase clutch wear if you drive it every day like you stole it. In other words, if you know how to drive stick your clutch will be just fine! Great product all around!

Rated 1 out of 5 by from Better ways to spend your money. When I first bought the Cobb AP for my 2017 AP it seemed to be pretty amazing. You can flash a tune on to your car and clear engine codes! Who doesn't want a faster car?! I installed the 91 Octane tune (took about 20 minutes) and went for a drive, monitoring knock which was all over the place. This is ONLY from a stage 1 with 91 octane top tier gas. Strike 1. I went back and immediately uninstalled at which point I noticed it was giving me an error code U112e/431a. I think nothing of it and "clear" it. Lo and behold, it doesn't clear. So much for that feature. Strike 2. Other than these it's an OK product, but also feels technologically dated and flimsy.

Rated 5 out of 5 by from Small unit Massive Power increase! I've had many Cars with 325 to 525 HP, & a few Turbo cars also. The Cobb AP stage #1 made my bone stock GTI feel like a Mustang GT W 425+ HP. While it may seem a bit Expensive? YOU get,- Super simple Installation, a small guage unit & Diagnostic unit, flash back to Stock, Valet, Upgrade & More! for me it was a no-brainer that Cobb was the way to go. I must admit I was going to go with one of the other 3 companies thinking the Cobb would be a weak underperformer. I can assure you, it produces more power than a reasonable person can expect! I'm floored at how FAST the car is now!

Rated 4 out of 5 by from Amazing after install First off...I love this product. All the trouble was worth it. That said the install instructions were at times confusing at best. I recommend not discharging and removing the ac. Just make sure you have something to support the core once the crash beam is removed. To do this I went and purchased a long partially threaded bolt that supports everything during the removal and allows you to slide it away with ease. Kind of like opening a book. I also recommend just purchasing the two clips before hand as these are easier just to cut away than remove. I have tons more suggestions but I’m tired of finger typing...I love this product. COBB really delivered. Stage 2 is awesome and makes me wish I had installed sooner.

Rated 5 out of 5 by from I'm very surprised I installed Stage 1 + in my car and now it looks like I have another car in my hands .... I'm amazed at the performance that my car got as COBB. Obviously by reading a lot on the internet, I'm afraid of harming my clutch over time. My car is a DSG and it should not be at all cheap to torque the clutch. I use the car daily and I confess that there is no way in a moment of the day not to accelerate to see the strength of my "new" car. I'm thinking seriously about Stage 1 + already recalibrating my DSG transmission. To avoid to the maximum any kind of problem .... Congratulations COBB. I'm a happier person today ...

Rated 4 out of 5 by from Great Intake/Terrible Install Intake looks great in the GTI, however the provided instructions were hard to comprehend. Please create a video with installation instructions, as I couldnt find any on youtube.
