I agree. The best mod I ever did on the car I raced/dragged was a data logger. Everyone else I knew who had one said the same thing. I'd feel blind moding a vehicle anything more than BPU without the ability to monitor all the sensors/motor.

I'm not sure how much a logger costs for the Busa, but considering the investment most people put into vehicles/bikes they race, the cost of the logger is miniscule in comparison to the amount dumped into mods and pays for itself in protecting your investment
