4. The tune is super fat, it's a header tune with stock manifolds.
5. I'll replace the plugs.
6. The fuel mileage was really bad, got 17mpg on my last trip, I'm use to 23 on my trips to Louisiana for work. I go 7mph over the speed limit, everywhere on cruise control.
8. I'll buy plugs today and set the TPS at .54vdc with a true RMS VOM also.

Thanks again y'all! Jay

1. 140-160F is where the engine management goes into closed loop.
2. The tune is probably NOT super fat. It may be richer although probably not at part throttle. Certainly not to the tune of 6mpg.
3. Let's see what the plugs look like.
4. And again, w secondary delete, ur second pump comes on at Off Idle, so ur sideways excursions shouldn't be due to the secondaries kicking in.
