Maybe his fingers went through the toilet paper and he had something really good to eat before hand and was wondering if it still smelled the same? Not saying I ever did this.

I wasn't worried. That was the easy trail. It was later in the day that truck took on all sorts of damage.

I rode in it on Friday with the 3" exhaust on it. It pulls very well but Im sure its very rich. We put my 14:1 FMU on it.

ordered the wideband the other day, soon as that shows up and is put in I need to figure what the air/fuel looks like and might need to swap out the fmu. I was talking to dave the other day and we might need to trick the TPS into thinking its at WOT at just a few PSI because the ECU is pulling injectors when it is not at WOT

Joseph Davis is credited with that trick if it works. I got the adjustable hobb switch today and a new map sensor.

well it works. I did the wiring this weekend on my Jeep and it ended up using a rheostat to adjust the voltage going into the reference line on the TPS. when i hit 2 psi the hobbs switch clicks and kicks the 5 volt wire down to 3.65v before it gets to the reference line and kicks it into open loop. So far so good, it is working well. running a little rich, around 10.5 so now I need to mess with the FMU.
