I thought it was Race, but when he got it it said Pro driver, 9% oil in it. I ran one tank, and I have to say it is too much power! Temps were low though, but I dont want to richen up my engine and lose my fuel economy just because I cant control it. My dx2.0 does not have a feature to smooth out the throttle response. Any suggestions? I also do not feel safe with 9% oil. I ran a quart of Trinity Platinum 20% (8% oil) and was to scared to lean it out. Could I put more engine shims to reduce the power or what? Any way of adding more oil? I would like to have around 10-12%, as I am just a club racer who needs driving skill rather than a powerful engine. Thanks!
