I played around with mine and it seems to run best at 12 deg., with premium fuel. It's been a couple of years since I installed it - no issues yet. Great mod. There seems to be differing opinions on manifold vs. ported vacuum. The ol' Jeep runs fine on ported, but I think I'll give manifold a try just for fun.

Performance Distributors builds the D.U.I. to run on the manifold vacuum signal so definitely give it a try.
