"Have a 2010 5.7L R/T challenger 6-speed manual, already with Corsa Sport aftermarket stainless exhaust & K&N cold air kit. Programmer appears to deliver as advertised. No pinging on any fuel on either "regular" or "premium" although I do have "residual" extra RPM with either setting depending on where the accelerator was prior to the up shift. No adjustment for that, intend to contact Hypertech for a an appropriate adjustment to the program." —Bill W from Bulverde, TX bought a Hypertech Max Energy Programmer for a 2005 Ford Mustang.
