I've actually tried 3 different Lozic TCUs.
Pressure 3 -5%
pressure 2 -5%
pressure 0 (stock), -8% (current)
My personal preference is the one I have now (pressure 0) because I like the stock shifting pressure. Based on all of the conversations I've had I would say most people would like pressure 2 or maybe even 1. I also like the -8% because the
3.3T makes most of it's power lower in the rev range, so the early shift seems better.
Also know that he can tune the TCU to match the Sport + settings in the new
G70 that maintains higher revs.
