I am not quite 400HP (390HP on Cobbs Mustang Dyno) but close enough lol

I get 14/21 and that is with 272 cams, GTX30, 91oct, full catless exh, open loop idle, P&P, ID1000's, etc.

BTW - how can I load the specs of my motor, etc into my profile so I dont have to type them out all the time

**Should note that the 14/21 was achieved on my 'econ mode' which is 310/278 for power numbers, I dont have gas mileage numbers on the higher power modes yet.
