m1008 lacking power at full throttle

I have gotten into the habit of trying to tighten those two nuts down more every time I open the hood. Just because the noise they make when loose is just not right.

After swapping the IP, I had the IP advanced about 2mm to the drivers side. After driving it some, I decided it seemed a bit too much advanced. So I backed it off to only 1mm advance to driver side. It seems to run a bit smoother now. Also I did remove the air cleaner to do this. Now that overbearing HOWLING has returned to normal...not sure which change helped.

I had a 82 civy blazer with a 6.2 and it ran alot better at half than full, just a 6.2 thing I think. I just but a 6.2 in my 95 gmc with 6.5 heads and turbo now that woke that 6.2 up lol

Oh man, I'm sure! Turbos are the way to go.

Was the '95 GMC originally a diesel truck...or did you convert it?
