I live in Puerto Rico and it never drops below 70F deg even on cloudy winter days.
His setup is this: Go .21 5PT, OS P3 plug, Maxy's 20% race fuel.
If we try to tune for lower temps it bogs and doesn't want to rev, and at the temps mention it screams with good smoke comming from pipe .

does this sound ok ?

The plug is good, if the air has very low humidity levels run a P6 this will give some tunning options as well as far as leaning it with lower temps, and helps runtime, run the 0801 pipe and your set.

if you have a trail of smoke and no performance issues like lean bogging then you are good.

keep a clean air filter on and you will get gallons and gallons of enjoyment!
