installed the DP tuner (happy) car shut off randomly (not happy). my impressions
I got my tuner and overboost eliminator in the mail today with a 60T codes and 80E codes. Looks like my truck was chipped previously as the silicone on the ECU was already removed. I hooked everything up, used some duct tape, and fired up the truck.
My first impressions with the 80E were that the throttle was very touchy and I'm not sure if I like how the tranny shifts. I do like the 60T though. I'm wondering why the 80T was mapped how it is, the turbo isn't boosting from idle, so why make it so touchy? It was raining today so I couldn't get on the gas like I'd like, but I was easily able to step the rear out (trucks don't handle quite like cars do
)
Anyways, I went out for sushi tonight with a buddy and had him drive the truck on the way home. He fired up the truck and turned the headlights on, immediately after he hit the lights the truck shut off. Very odd...I doubt it's a loose connection. Any ideas?

You won't get any boost from idle with any tuner or tune selection. One when you are under acceleration or pulling a load will you see your boost gauge indicate psi pressure.
If you drive like with a raw egg under go-pedal, then the 80e tune will shift rather nice. When I get a heavy foot in that tune (which is my everyday tune for my truck) it will shift funny at around 45 MPH when the TC locks up and the O/D kicks in. Those two events are a little close.
As for the touchiness of the throttle, that's just you having more power under your right foot.

My opinion is that the EMI is causing the chip some grief. There is no microcontroller on the chip board to switch the memory allocations on the memory chip. It is all done in the switcher and any interruption in the signal from the switcher to the chip will cause "confusion".
Give a re-route a try.

Re-route the switch cable. My thought is that you have the cable running next to some wires that are inducing some EMI into the cable.

Yeah, I got it from Jody. The switch is mounted yet, it's over my trailer brake controller. I'll be mounted when I get my a-pillar mount.

Well, from my experience, if the truck isn't under boost, you really can't gain much from a chip. Don't get me wrong, there is definitely more power under boost (I can see this on my boost gauge.

Of course, the switch cable has got to come out of the back of the PCM. However, try routing the switch cable away from other wires in the truck...especially high-current ones like ignition switch wires or headlight wires. Also, you might experience some problems with the switch right next to the brake controller if you have a trailer hooked up....there is A LOT of current there.

And IIRC, Tom's truck would die when he turned on his driving lights after they did the bumper install at RRE. Not sure what came of that.
