Well, a reasonably priced option is to purchase one of the tuneable ECU's from Chris Ludwig.

I was chasing all sorts of weird fueling anomalies and actually had the opposit situation in that I ran rich and the motor went all soggy at high RPM.

With a wide band and the programable ECU all is well and can be pretty much dialed in to exactly what AFR I want at what RPM. In a race application pretty much interested in WOT but there are other pieces of the map that are valuable to smooth out also.

I've NEVER been successful with such high fuel pressures as some other folks recommend. I run on the high end of normal (40's) and granted I'm not a Huffmaster but my car does pull strong and clean with all it's got to offer.

Talk to Chris (Ludwig Motorsports) the ECU makes a world of difference.
