high idle after WOT race
hi, i got a 2009 raptor supercharged, it is running very well now. the only problem is that after every WOT race when I shift it to parking or neutral it rev up up to 2000 RPM for about 20 secs and then start to drop back to normal idle. any idea how to fix this??
thanks.

IDLE RPM IAT ADDER would add a few hundred RPM if you got your engine coolant hot. Shouldn't be adding that much though.
And/Or You got the catalytic converters so dang hot that the enrichment required to cool them back down is elevating your IDLE rpm.
