Wel folks i ran it up today at work with an os plug and got a more consistant run than with the traxxas plug. IT would hold 16.6-16.7 without wavering much. I ran 2 more tanks of fuel through it just to verify these results. Remember now that the engine im using is a 049 tee dee with a KK needle on it and a KK tapped cranckcase cover for fuel pressure. Your results may vary.
