How do I get 400whp reliably in 7AT 2011 370z

Jordo!

To the best of my knowledge, at least two boosted 7AT's have failed. Whether those failures were due to tuning (e.g., shift firmness can be tuned) or mechanical limitations (i.e., gears simply failing from over power) remains unclear.

My advice would be to call GTM, do some searching, and spend lots of time thinking and considering before proceeding.

Good luck!

P.S.

You can get it to 300 whp pretty easily tho -- check out my dyno thread. Search for Proven Power.

EDIT: There, happy? Nothing misleading here.

The quote below is part of the UNTRUTH being spread on this forum. ONLY 1.....yes 1.....7AT has failed so far and it was on an SC install. It belonged to member shumby and he was a very early adopter of FI. I have talked to him through email and he has stated that his install WAS BEFORE they knew they could tune the tranny on the 7AT. His car was also very high miles before the install. I have been running 490rwhp on a twin turbo setup on my 370 7AT for over a year with no MAJOR issues. Sam@GTM would be the best person to talk to on this subject. BE AWARE that the 6MT guys will bash this tranny and will tell you cautionary tales that are not true. Many people on this forum are running 400+ hp on their 370 7AT's.
