I was looking at this air/fuel pressure regulator. The ARC2 A/F Ratio Calibrator. I was wondering if any of you have one. Would you recommend getting this at all.

Its not gonna gain you anything in terms of horsepower on a stock engine and not much on a modified engine. Its more to tune the engine and make sure it runs with heavy mods.
