My age and lack of technical and new information is glaring. What is, "30 DS and Ripped in 30 back to back and then switch to insanity or turbo fire?" It sounds like a foreign language to me. An answer will help me be less in the dark ages.
I am a commercial pilot, and turbos is a type of airplane engines. "Insanity" is a word for people who need to go to a home for people who have lost their minds. As for "30 DS" I am clueless.
I must be getting old....(now age 55)
