i still sauy its way overpriced for what you get, and as for p8 reliability issues, i cant complain about that mine has been fine, and as for the cost of a full spec P8, comes nowhere near that of the modded L8 sorry.
at the moment you might as well be buying an S8, its an unknown quantity, just because a handful of people have tried it and say its good does not even come close to a factory P8 , for the average cosworth owner its not cost effective. for the tuners who can already work factory L8, P8 etc its still not cost effective, and ALS, on RP labs, does this actually work now, and is it actually on the ecu ???
