Attention: TDR Forum Junkies 
I have replaced the injectors and #1 came out coated in heavy carbon. I'm talking chunks fell off the tip into the head when I removed the injector.
I made the test tee/orifice and ran the test on the highway. Running up a small grade, with the truck in tow haul mode, boost at 27 psi. and the ac compressor doing its thing with the defroster, long petal on the floor. At 2,800 rpm i recorded 22"wc that converts to 131 Lpm. The test was repeated 3 times. Truck has 82,000 mi. Is this a good number for the miles, or did the bad injector shorten the life of the engine. I did turn on the Banks tuner and the boost did climb to 40 psi. Test results were the same. FYI, head studs are on the way. Injectors are BBI 0.5 tow injectors.
