FPVGT, read the question, which was:

In terms of performance, The BA 6cyl will benifit performance wise
by using PULP, only if you use it exclusively so that he EEC "gets used to it", and we're talking a very minimum increase in performance here, something similar to changing the standard air filter to a less restrictive one like a K&N. The BA V8's will not benifit performance wise
. No you will not gain faster 0-100 or 1/4 mile times by using PULP in a BA XR8 unless your engine has been tuned for it by means of a chip or soon to be Boss Edit. Even then, it's not going to be much. The 290kW BA's are tuned for PULP already so no gains there anyway. Where did I say any car, regardless of having knock sensors or not will not benifit by using PULP? They will benifit in other areas, but in regards to a increase in power/performance, no they won't
I use Optimax exclusively on my 220kW TS50, 'cause the engine was built for PULP. I once did fill up with normal Unleaded (Ex GF accidentally put in ULP) and the performance/power did drop. Couldn't go past 4000rpm without engine pinging. If I had a knock sensor it would have backed the timing to stop the pinging, but I'd still be down on power. Likewise, an engine with a knock sensor will adjust itself to the fuel being used. If it happens to be a higher octane rated PULP being used, the knock sensor will advance the timing at high rpm 'till pinging then back off slightly, thus giving a increase in performance. Knock sensor isn't there for performance gains? Yeah right!
