It is not getting, it is fast, just need ......................., that is all. Chris did it!!! and you will do!!!!!!!!!!!!!!
Just kidding. PS12 has different type of tunning. Ones you tune it according to recomendations-it is realllyyyyy fast thing, but if you will try on it apply Novas based tuning techniques, it will not be very fast. This engine has different design and it is required to run much leaner on the bottom. It is related to timing on induction and temperature transfer rates all around the engine.
Pretty easy and totaly different from conventional desings.
Just for instance, ones it tuned right, head ( glow plug area) temperature is about 230-240 but bottom part of cyinder and crancase never reach even 190-so , whatever has to be hot is hot, and whatever has to be cold is cold.
