I have a very long highway commute to work and boy did I open her up on the highway today. I have the auto and have noticed quicker shift response much smoother engine sounds at any RPM but very smooth at the top 6000-7500 where it use to sound a bit harsh. Every gear seems more useful again due to more torque in the mid and low end.

For those with the 370z 7AT this is a must have if you have bolted on the HFC or Test and CBE. An unexpected plus is the downshifting when in Manual mode. The car use to shift very hard into 2nd then 1st when coming up to a stop sign (Letting the car downshift on its own in Manual Mode). I don’t feel this anymore just nice downshift no abrupt gear change. Thanks again Mike and Clint for hooking me up with this Canned AAM Competition tune. The Cobb Access Port is a great device loving the data monitoring and performance monitoring, I can finally see what my car is actually doing!
