I can also tell you that retarded timing with WMO is like the kiss of death. The Moosestang's IP is now worn to the point where I have it cranked all the way over and it's still not advanced enough. As the condition has worsened, I am now seeing EGT's skyrocket under even the lightest throttle settings. If I floor it on level ground, I can get to 1200 in a quarter mile.
My fuel milage is probably down around 10, from an original of 17. As soon as that funny government check comes, I'll be getting a new IP and injectors for it.
