The dyno we use has issues with the wide band sensor. We always use our own wide band to tune (Innovate) and it is not hooked to the dyno. The A/F was mid to high 11's. and going lean on top where the power was dropping off on the 30 PSI run. We used a Custom test clutch because the customer was out of money. It was a RPS MAX 4 puck.....Less pucks = more holding power because there is more pressure applied to the pucks with less area. The clutch held well and has 16K miles now and is now starting to slip. Lasted longer than i would have thought. We can have these made for anyone wanting one.
