Toyota said the power increase comes from a new six-port dual-branch exhaust manifold (last year's model had two ports), revised heat management, and a new piston design that reduced the engine's compression from 11:1 to 10.2:1.
The increased power output also increases performance with the last year's 0 to 60 sprint of 4.1 seconds dropping to 3.9 seconds, though top speed remains electronically limited at 155 mph.

But we know supras hp of 335hp wasnt the real numbers. When it was dynoed, it was closer to 400hp. So the question is, is it just a software tune? Ecu and maybe a TCU tune?
