Where did my low end go?

I think he meant the MAF sensor, which detects the amount of air flowing into the intake. A MAP sensor detects manifold vacuum to determine engine load. If it malfunctions it can cause the ECM to think the truck is coasting when it is actually under load, so it can affect performance negatively if not working properly. I don't think any of these trucks have a MAF sensor, though.

The second video doesn't sound very good as the camera I was using wasn't great.

"Here's the combo, previous bolt-on mods first. 50mm F&B throttle body, K&N round filter with Xtreme-style lid, Mopar plug wires/Accel coil/NGK plugs. Magnaflow 3" high flow cat/Dynomax 3" ultra-flow muffler. We just installed a set of used, unported 1.92 Mopar Performance R/T heads with a fresh valve job/seals, etc, used Crower 1.6 rockers, March steel underdrive crank pulley, Edelbrock shorty headers (still using factory y-pipe with pre-cats. Factory kegger intake, not modified, with Hughes billet plenum plate. Dyno tuned with an SCT controller."
I don't think I'd call all of that cheap OR easy.

I'm not saying it will solve the issue, but it may help a tad. MAP helps the computer control the injectors IIRC, and if they aren't pulsing right, your engine won't be running quite as well as it could and you won't have quite the take-off you would if you had a Grade A condition MAP.
If you have access to a tuner that can clear codes or a scanner that can clear codes, unplug the MAP sensor and see what your truck does when you try to start it and what happens when you try to drive it.

Don't worry about it, that's a very sexy sounding truck...
What should I be looking for when I unplug it?
zman17, please let me know what happens when you install the new sensor. Thanks
I guess I could start messing with the exhaust flow, but that's kind of a pain in the butt for something that may not even work. If anyone tries this please let me know how it turns out.
