FI vs. stock NISMO exhaust, In for a penny...

I gained a little over 30HP with the mods in my sig. Not to mention how awesome the F.I. + HFC combo sounds.

Hi Kris, I am looking into purchasing a 370Z Nismo Tech 7AT like yours.

Just wondering, did you ask UpRev to also tune the transmission to improve shift speed? If so, how noticeable is it, and how do you feel it will affect the durability of the transmission over time?

As for the performance tuning, did you do it remotely (without dyno) or with dyno runs?

Thanks in advance...

Ha well he may not answer as this thread is super old but I have a z with 7at and went ecutek route with Seb a specialty z just recently. The shifts feel good and seems like there is less hesitation on what gear to choose at lower throttle / cruise. Oem had kind of a spot on decel when it would do a shift down then back up like a 2-1,1-2 shift if you were just very light on throttle like slow cruise down residential street. It doesn't "bang gears" or anything like that and is still great for street driving, just maybe slightly and very slightly if that a more positive shift.

As for wear, well in theory the clutches should last longer as they are engaging sooner and have less slipping (easing into the shift). Other car lines that have the dual mode normal and sport for their shifting will last longer in sport mode for the same reason. Think of it as slipping the clutch on a manual vs letting it out quicker and engaging sooner. Taken to the extreme either way one will burn out the clutch and the other outs more stress on the gears but find the right balance and they will last a long time. Personally I think the autos with only 1 mode always error on the slip side as customers also persieve anything positive / harsh as wrong.
