Sprint Booster review for 370z 7 speed AT

I recorded some clips showing how I can break loose my tires on a roll in 1st when "cool," record the speed the car revs up in 1st and 2nd, and then show it again when things are "hot." The video will show you that on a roll in 1st and 2nd, the car revs up slow as if throttle isn't even opening up. That's why I don't think SB will help my situation.

I'm perfectly fine with the throttle response of this car immediately once the car warms up after start up. Then after driving for awhile the throttle response becomes sluggish to the point I find myself trying to give it more gas to get it to go anywhere. It's bad when temps are hot out there.

Sorry for going OT in this thread, but just to make things clear about throttle delay versus not getting power when applying 50-80% throttle on a roll. I'm going for another test drive with the tech this afternoon since it's warmer.

[EDIT] Drats... had to reschedule. Hopefully it doesn't get any colder.
