Now, don’t get me wrong - I’m not hot-doggin’ this thing at every red light or anything, but to me the truck’s performance is so restricted as to be nearly dangerous. I strongly suspect that this is to eek out the last 2/10ths of a mile-per-gallon in the Federal EPA MPG test or to squeeze by some dumb phoney pollution dynamometer test.

I have also noticed that the cruise control is so deadened as to be nearly useless - you tap upwards on the control 6 times for 6 mph to be increased on cruise, and you get maybe 2, sometimes 4 mph. The truck completely refuses to downshift if climbing under load, so it will stay at one speed or even slow down.

I was hoping the device would give me normal performance from the currently sleepy throttle, and guess what?

It works PERFECTLY - I have just set it up on the stock setting (Mode 2 - “Power,” range 6 of 9,) and the truck has a throttle that feels like a conventional vehicle - downshifts appropriately, stays in gear until it’s generating some RPM for the next gear, etc.

Cruise now works exactly like it should. It will downshift to maintain speed, accelerates like a normal vehicle to resume speed, and I am having no problems or challenges with any acting up/check engine lights.

I am checking MPG this week to see how badly it will be affected.

Installation was initially a bit difficult - the plug on top of the pedal was quite hard to get leverage on to pop off; the retainer clip is in a difficult position to reach for the release of the clip.

But beyond that it was straightforward, and setup was nonexistent.
