Thank you al for all the comments, gave me good advises to operate well my GB engine, that is not easy. Of course I am following the Turbo-Plus STC and adjust the MP by the chart they provide, looking at the temperature decrease by the intercooler. One new questión would be if the CDT probe should be moved to the intercooler air exaut, so I really get the real temperature that the cilinders are getting in.

I bought my M20K 231 without both TIT an CDT with cutted cables and only a JPI 700 to bad track both parameters. Just in the firs hot day my engine went into detonation, and I can tell you won't like to experience this situation since it was sounding that the engine was going to get all apart. After that I decided not to fly before the restitution of the old indications. Now I have TIT indication working perfectly after installing new cables that insane where cutted at time of installation of the JPI engine monitor. Still I have to restitute the CDT indication, but since my 231 have a Turbo-Plus intercooler. Can anyone can tell me how reliable would be this CDT indication to avoid future detonation in my GB engine?.
