On the 5AT atleast with uprev they were unable to remove the speed limiter so you can't get a complete run in 4th. Most people dyno the 5AT in 3rd anyway. The tuner might have though it was a 7AT. Mine did because the 370z he did was a 7AT so he just assumed all g37s were until I told him it wasn't.
When I had my tune done I didn't not have a stock baseline dyno ever done, but baseline before tune was 291 and final dyno after tune was 298 in 3rd gear. My power curve was a lot more balanced after tune and in the midrange I had a max gain of 18whp. My tuner made an estimate based on the dyno results of the car that my car is pushing about 315whp in 4th although I can not yet dyno in that gear.
My buddy tuned his 350z (VQ35DE) with mods including JWT SRI, plenum spacer, NISMO Headers, test pipes and NISMO CBE. His max power after tune was 275 with his 6mt trans. He just added the MREV throttle body and is waiting to be retuned, I will report on his gains when I get the results.
But as you can see from my buddies numbers you are not that far off from his, even with all his bolt on mods.
