The first step of my turbo build is in the mail. Wide band next week, then its time to build a motor. Between then and now i am gonna tune my B16 and get some cams and valve springs. The only question i have is about the interchange-ability of maps between neptune and crome pro. Both programs offer the same options and capabilities. However, i had my friend send me the map he uses on his turbo teg and i couldn't get it to convert. He uses crome pro and the file for the map is a BIN file, neptune is an ncl file. Anyway to convert? Probably won't need to because neptune comes with quite a few stock maps but i figure it might be use full.
