testing stg2-UEL for OFT. Previously I ran stg1 - 93 oct. Fuel here in méxico is rather ambigous. Some say premium unleadead is 93, some say is 92. In any case, runing with 93 tune engine looses power. Now runing on 91 tune I think it lacks proper timing. Engine stalls more easily, you need to give it more gas ,and so on.
