Thanks for the response, and yes the truck idles slightly rough but liveable, but the throttle is fine. What i would like to accomplish with a tuner is no smoke, smoother idle and more power with better EGT control. I forgot to mention that i do have a Banks 100hp chip which gives more power but with the associated smoke(not alot but but i think it can be reduced). I want more selective control over the power. The PO put alot of the mods on this truck so i have been slowly changing them to my liking. As for the injectors, from what i was able to find out was they were done by Diesel Dynamics (out of buisness) so short of pulling them all had having them flow tested, not really sure. I did find out from the shop that installed them they were "80hp modified" but that was all they could tell me. If we have to go back and forth a few times with tuning so be it. Need to get my new turbo back and see how she runs first. Good luck hunting. Roy
