Getting the power to the wheels

Meant to ask you when you say "breaking up" @ 5800, you were on a dyno correct? If so the operator most likely/ should have had a O2 sensor on one of your sidepipes. I'd ask him what the AFR changed to at that moment just prior and then @ the breakup. If it leaned out I'd start looking at your fuel supply (Old hoses, filters and the like). Ethanol is not kind to rubber.

It was leaning out. Car isn't old, and engine had about 1000 miles on it. I had a wide band on the exhaust. Need to get the print off to compare with factory.
