What's wrong?

[sweet97]

Tuned for an 11:1 A/F and running 20PSI with timing in the upper teens at redline, no knock. Just doesn't pull. I suspect the Spearco 2-221 FMIC is not efficient enough. I have a temp gauge to install the sending unit in the elbow before the TB. What should temp be over ambient with a good FMIC? Mark

Have you tried adding a little fuel back in? On my car I can tune all the way to 11.5:1 with no knock, but it pulls harder at 11.1:1. I haven't tested this at the track or on a dyno, so I don't know if it really makes more power but it definitely feels stronger at the richer setting.
