yea i've tried P8 and noticed much more top end and maybe 10 deg F cooler. but the bottom end seems not that responsive so i tried P7 inwhich i prefer. i think i might have to play around with my gears as well. maybe as i lean it, its hitting top speed quickly and staying there for a few seconds which might be the reason for being abit hot.
And Luis im getting a guy at my track to do the mod hes been in this hobby for 10 years. and hes motors go very very well! and very very reliable as well.
