Maybe you got a bad unit. Try removing it, and see what that does.

does it matter if the mp-8 feeds the juice? or does it need to be vice versa??

Plugs in between the harness, so you can't hook it up wrong. See if unhooking it makes a difference.

Just like diagnosing a computer problem. Unplug hardware until it runs stable.

crap i think i was using both i cant remeber. im almost 4 sure i had both in. but ive read other threads that sometime it matters how you have them plugged in. try unplugging the juice and have nothing in and see if the truck runs fine then try just the mp8. see what happens then. maybe they dont like each other?

How do you like the MP8 ? I sent my smarty jr back, I didn't like the timing rattle I was getting and on the 70 HP setting the truck shook when at idol the 100 HP setting was great but smoked way too much plus I saw no milage increase at all.
