The VP12
The VP12 is our most powerful Dynamic Soft-Flasher. Operating at 20MHz with plenty of On-Board Memory, the VP12's 8-Bit CMOS microprocessor offers extended compatibility along with faster patching for safer, higher, and more consistent gains.

Gains
Average gains for the C-Series Topkick are 10-19HP, or up to 25HP depending on your current modifications. Aftermarket intake, exhaust, and other mods will improve gains. For a more precise estimate, we've created a simple tool on our website to calculate gains given your current modifications.

Installation/Use
Installation takes about 15 minutes and requires no special skills. Once installed, press the RESET button to calibrate and you're done!
The VP12 does NOT include an OBD-II connector. It connects directly to the OBD-II port's data lines. OBD-II scantools will not interfere with operation.
