Hi Phillip.
Yes we have made already P/S sets for Picco based engines and they are in testing process now. I don't know yet when it will be available, but untill we tested completely for power, durability and reliability we are not going to realise it. Also Picco engines are not realy popular and till they pick up market, I don't see reason to make stes for them. Let's see-time will show.
About Mark's engine was quicker on acceleration-if you were running with 0.8mm head clearance it is diffcult to have quick acceleration. Change clearance to 0.3-0.4 and try-I am sure you will see big difference. Last weekend we had Toys for Tots race and there were lot of big names-Ofna team, Mugen team, couple Kyosho guys, RD logics etc, but nothing even come close to the performance of REX RER with BRB on MTX3 (not JP. not Picco, not REX TUNED). Actualy it was open race, so any engine was allowed to use-3 ports, 5 ports, no carb restriction-everything went.
