totally agree... my mate Michael and I are slowly learning on his dyno, finding many different procedures, ALOT of trial and error, managed some very good power with a very safe tune so far...mainly working with PFC's and Microtech, still waiting on my PC interface for PFC however.....but yea many procedures, safe guards to learn....alot of tricks and ways of not doing things are involved....takes hours and hours of playing with and with the right people.
