So I bought a CTS Insight, Got it all hooked up and such.. Check the injector rates, #3 seems to be running a 5.3-5.5 in park all the others are around the 1 mark or -1.... Truck seems to run good, I do have a Bull Dog programmer on it,that came with the truck when I bought it alittle over a year ago... The injectors were replaced around 215k miles,and I have around 235k on it now.. Any thoughts?

That I am not sure, There has always been a 3-way switch under the dash.. Forward,middle and all the way towards you.. I have it in the middle, I think Pulled back to me is stock tune... I have been wanting to get rid of the Bulldog and get an EFI Tune for the truck.
