that venom control module is a piece of shit. All it does is tap into your throttle position sensor and tricks the ecu to thinkin that you're giving it more throttle than you actually are. So when ur at 3/4 throttle your motor will be running as if you were at full throttle.

Your in luck though, theres a free alternative to the venom control module, that is, step on the gas more.

As for improving your motors power, you most likely will not be satisified with anything but a turbo. An intake and header are a waste of money on a d-series.
