Not much road time on them yet, but so far I'm VERY impressed. This is my first set of aftermarket injectors, so I don't have much to compare them to, except for my EZ. I was very concerned about how high the egt's would be with 100hp injectors, but that turned out to be no big deal at all.
I had initially unplugged the EZ's data connection (to save the stock clutch) and left the MAP portion plugged in to keep the boost fooler. After I fired it up for the first time and all the lines re-primed, I couldn't believe how smooth the truck sounded at idle! I had a slight "romp-romp-romp" when feathering the clutch while backing out of the garage, but with the pedal all the way in or out the idle would smooth back out. Acceleration smoke is very controllable, probably more so than with just the EZ (it is only 25 deg F out though). Heavy acceleration with low boost would get more smoke than with the EZ, but once boost built (over 10psi) it was clean burning.
By the time I reached 90 mph on a full throttle acceleration run I had 32 psi of boost and egts were barely touching 1100 deg pre. This compares to 28-30psi and 1050 deg with the EZ and 22-24 psi and 1000-1100 deg stock. As far as power, I can break the duals loose with long-pedal only in third gear on dry pavement. The girlfriend talked me into plugging the EZ back in at the lowest setting, and that ended up breaking the rears loose in fourth and resulted in 34 psi and 1100 deg @ 90mph.
So, like I said, I'm very impressed. I wanted to add power but keep the driveability and towability and I think this should do it. The clutch holds for now, but I will be getting an SBC OFE in the near future. Of course, that would allow me to put in a DD UFM and a 40/35 turbo... . When will it end?!?!
