My truck's engine dies when I plug the chip in. I bought a new computer. I have tried different chips, one without modifying the stock program. The truck ran a chip for 10,000 miles before swaping the engine out for one that was built.

Please put me out of my missery!

 

"The eng. dies when you plug the chip in "....the neg. battery cable should be disconnected when plugging the chip in--or did you just misstate what you did?
