Message: [QUOTE="jopes1, post: 1508110, member: 29854"] Blew hole in piston and put a new engine in. Reman 180/100 injectors were put in before 1500 miles before engine went out. After about 250 miles my chip lost heavy tow and economy / light tow. Right up to the day I disconnected the batteries to pull the chip I was getting 25-28 psi boost and the truck ran fine in the higher power settings as well as the high idle. Get chip back and now I have no power in all settings. Idle is not as smooth and idle is high by about 100 rpms. Also seems like the idle is louder than it was before I pulled the chip. Icp is 3200 @wot Boost is 8-12 psi Fuel pressure 55 Map sensor is reading boost New ipr when I did motor Ford under valve cover gaskets were used when I did injectors When I lost the two tow settings I removed the chip and recleaned the ecm. It never changed. Last night I drive it and it didn't have power. Stopped shut engine off, 15/20 seconds later I restarted it and it ran fine as in 28psi boost till I shifted into 4th gear. Then it fell on its face again with 12 psi boost. Ideas on what to do? Is the chip faulty? Something else a issue? [/QUOTE]
