Truck seems to lack power. "slow" to build boost in my opinion to what I am used to. Checked all of the usual things (ICP, fuel pressure, up pipes, charge hoses, TPS, etc) and I've come across odd map readings. I have a boost gauge tee'd into the MAP line going from the intake runner. With the line disconnected I get 0psi on the gauge and 0psi on the map sensor. Pressurizing the line with shop air to 20psi I sometimes get close to 20psi on the map sensor according to autoenginuity, other times I get 0psi or somewhere in between. I don't get a CEL at all, zero codes when scanned with autoenginuity. Took it for a drive, large hill on a 2 lane 55mph highway. With or without the map connected I got about 14psi max (which is ok for stock) except it took a LONG time to get there with the pedal floored and o/d turned off going 70mph @ 3000rpm. Floored the HPO is 2500psi and 36% duty cycle. I tempted to order a map, except the motorcraft OEM is about $100, and I'm never a fan of throwing parts at things.
