Does anyone have any experience of the "P" version of the 710? R-tech advised I go for this when I enquired about pre-map freshen up work (1.8t AUM) and that this is the latest valve that TPS would sell me.

But, my local TPS (Slough) only keep the N as stock. Looking online, there's not much info except a few posts stating that the P is the stock valve on the old RS4(?), some even listing that the P is inferior to the N.
They can order me the P if I wanted so

If any one has any views or personal feedback that would be good.
