[QUOTE="POWER-STRUCK, post: 1185250, member: 9487"] massive pulse widths along with advanced timing at lower rpms are likely the cause of premature PMR engine failures. some older styles of tuning had massive timing advances to help with responsiveness/ smoke control (hoping for hp and economy gains). in my opinion if low boost fueling is controlled correctly most tunes can be smoke free yet if low boost fueling is limited excessively the tune could have a light switch effect. each tuner has their own opinion of how to control each parameter, in this scenario the tunes should be chosen by how you personally would like the truck to respond.
