Im kinda new to the whole performance side of diesels (seeing how the old GM 6.5's I used to run had nothing to do with performance) but that being said Im not trying to make "smoke" but with my 07.5 cummins i did the three major bolt ons and it doesn't smoke. So im wondering if i should be worried that when i turn my programer up to the hot setting it doesnt turn into a misquito fogger or should i be happy and think that means its running efficiently also if any one has any advise on other cheap fuel economy boosters they would be appreciated

 

Id be happy if it performs how you like it and noticed a power increase. ALOT of tuners these days are making cleaner tunes that make as much power without the smoke. Id be happy

 

agree
