Hey has anybody bought any tuners like a access port for there infinti? I have a 2011 g37s and was wondering if anybody has a computer tuner for it? If so did you notice big gains in horsepower and torque? What kind of tuner did you get as well?

 

The only thing like an access port for our cars is the Hypertech which is decent if your keeping your car mostly stock. It has a map variation for short ram or cold air intake. If you plan on putting stuff other than an intake on the car like exhaust, hfc's, intake manifold then that device will hurt more than help performance.

 

If you're doing other breathing mods, definitely look into finding a reputable shop near you that has experience with UPREV tunes. YMMV according to your parts, but picking up another 20-30 HP is not uncommon as long as you have good mods to go with said tune.
