Power Loss
After my car was tuned about 4 months ago it ran 7.0 at 99mph in the 1/8 mile afr was 13.1 at that time but now the car has slowed to 7.2+ at 95-96 mph and the motor is running at 11.4 afr at WOT What would make the tune change? How long is a tune good for?

Did your tuner eliminate COT protection? If not the
car can kick into a fuel-dump mode any time you
get to romping on it. If you have picked up some
jacked fuel trims that could also push WOT fueling
around. Scan it and see, if your trims look tight then
I would suspect the COT kicking in (unless you know
otherwise, for sure).
