R35GTR modification .......................already many people started....So we try with one of the most popular mod. Computer tune with COBB ACCESS PORT.
Comes with connector and controller!!
This system is very easy.......down load data from their web site and send it to vehicle ECU.
And instant power up.......we tryed with stage two(full exhaust system).
This car didn't like our Dyno machine at low rev(too much load may be), but obviously gain the power at whole range. 60Hp at wheel so over 70Hp at flywheel. Magic engine!?
