TPI Questions

[George M. Dailey]

Ah ha! That's probably why my milage was so bad with my TPI set up. On
advice of Peter F., I attempted to bump it up to 12 btdc. Ratteled like a
coffee can full of 3/4" marbles. I discovered that I had it set at 4 degrees
and was able to bump it up to 6 degrees without detonation. Picked up some
extra milage too, I'd say I'm at 13-14 mpg city now. My EGR is disconnected
due to a leaking actuator. Maybe I can bump it to 14 once it's repaired.
Thanks again Peter.
