Rated 5 out of 5 by from Like an alarm clock! This device woke up my GT-R like night and day. My 2015 is bone stock, but using v700 stage 1 and a custom TCM tune, I now have an extremely aggressive Beast. This tuner made my car drive like it should!

Rated 5 out of 5 by from Awesome product Great product I'm an auto technician for 27 years now install was a piece of cake took me a little over 1/2 hour to install intake system and 5 min to install the access port. running 91 ACN map with shell v-power 93 oct because that's the only map that works don't know why? Can't get boost under control with any other stage 1 map? Maybe you can tell me how to control boost? Problem is car pulls to much boost over 20 psi so it pins the boost guage and car shuts down, probably from knock detection I'm assuming. still playing around with it but if you can give me some help that would be great.thank you

Rated 5 out of 5 by from Fantastic! Great Product and user friendly. My 2015 GTR is still bone stock but the off the shelf Tune for 93 octane woke the car up big time. I think the power and torque is right in the sweet spot for a stock engine. Next steps are better sound with cat back and intake. I also purchased the transmission tune. What a difference....the shifts are smoother and more precise. The combination engine/trans tune is well worth the investment. You won’t be disappointed buying the Cobb.

Rated 5 out of 5 by from Updated TCM shift points are AWESOME!! I waited for a while before buying a tuner for the car - when I saw the video demo-ing the new shift program, I was sold! This alone would be worth the price of entry but add to that the extra power and fun "whooshy" sounds from the turbos and wastegates that you can hear make it so much fun! Mine is actually stage 2 now with the midpipe and tune and holy cow is it fast!

Rated 5 out of 5 by from 2015 GTR Stage 1 & 2! I recently purchased Cobb stage 1 (tuner and BF intakes) for my 2015 Nissan GTR. I already had a HKS Y-pipe from my previous GTR to go to stage 2. The key features that deliver value for me include the Nismo TCM shift points and the stage 1/2 maps which are supposed to deliver 100hp to the wheels. This is a no-brainer and is a very cheap way to take this car to a whole new level. Nice work COBB team!!

Rated 5 out of 5 by from Wowza! This tuner woke my Gt-R up! It was already fast but this made a huge difference in all around power! Pretty easy to use to even for a technology challenged person like myself.
