Took about 30 miles this morning to throw a CEL, P0171, LTFT seems to have stabilized at 28-29, but when stopping or coasting it drops to 2-3. A/F doesn't seem to change ever so going to investigate that a little more this weekend.

With E10 the HP went negative when DFCO, doesn't go negative with E55. Did a 3rd gear pull uphill, saw 102 hp at 4,000 rpm (55 mph) before shifting to 5th. HP is pretty slow to update so really the same as E10. Need at steeper hill or more weight in the car to make the pull take longer.
