Review on Pedal Commander PC77 Throttle Response Controller for Chevrolet Silverado (2019) (4th Gen) Gas Engines (1500, 2500, 3500, LT, LTZ, RST, WT, High Country & All Models) 2.7L - 6.6L by Keegan Herbert

This thing nearly destroyed my 2019 Sierra Denali. Installed as instructed and started the truck only to almost reduce RPM. Disconnected the accelerator harness and returned it to its original position and all possible fault codes appeared on the ECM. Had to rip out the OBDII reader and clear the codes several times, finally had to disconnect the negative battery cable for 20 minutes to clear the ECM. I called the seller, they told me they sent me an unupdated firmware. No thanks, sent back. I'm already squeezing out 430 hp. with this 6.2L LS3 and would rather not blow up my $70,000 truck because this thing is not tested before shipping.
