Do you guys think 12.75 is too rich for my car? Should I back it down a bit?
I'm going to check my plugs here in a few when the snow storm clears.. when some of you guys had it where did you get the best results?

From what I've seen the extenders aren't always that accurate. People have had them at 12.75 or something and then on the dyno they're at 13.5:1. The only way to know would be to get on a dyno with a wideband.

I guess it's just that time of year when I feel like my car is slow. Just wondering if I could turn the dial a bit more or not.
BTW: The nearest dyno is over 100 miles away and it's not open when I'm not at work.

your FPR will play alot on the air/fuel ration as well. I think I have my extender set at 12.00

I think I may crank mine down to 12.50 or 12.25 and see how it does.. and check my plugs when this crappy weather goes away.
