I recently decided to make the move and add some modds to my car and attached results for those whom are interested. My car is a 2013 G37 XS coupe 7AT. First I would like to say that I made the decision to make alterations for simple drivability. I love the car but was unhappy with crazy shifting and erratic behavior of vehicle sometimes, so I decided UPREV was the solution; however, I was not going to get tuned unless I made some basic modds. Well here are my results: 330HP and 277 Tq. I had tune done at RT Tuning in Landsdale, Pa and owner Vince did mention that numbers are a little skewed due to Mustang dyno. He said my HP was probably more like 312-315 but I am still happy with that. He stated that with the new software with UPREV that they are able to do a lot more with timing hence the higher numbers. As far as drivability, I notice a lot of changes in the vehicle. Even when I had the GEN 3 and CBE installed there were some minor changes in the way the car drove but the tune definitely amplified those changes; smoother shifting, quicker throttle response, sound, etc. I have only had done for 2 days so mpg is yet to be determined. For those of you who are on the fence about making modifications as I was, I think it was good decision. I wanted exhaust that was not loud or obnoxious with minimal drone (huge concern with 7at) and I feel I made the right choice with Stillen. I hope this helps.

Id say the dyno needs some recalibrating. Lol seems way high

Even with corrected values I doubt your number would be that high with those two bolt ons and an auto. And Mustang Dynos are among the lowest reading dynos. I predict between 290-300 at best based on my experiences and research.

FWIW, my car output 314/275 on a Dynojet with more mods and a solid tune. 6MT.

My baseline before the tune was 295/250. Here's a link to my thread with mod list.
