Will setting the low boost fuel on level 5 hurt anything running the edge juice/attitude on power level 3 and stacking witht he predator set to tow mode? I would like to leave the low fuel boost on level 5 for the smoke factor, I just dont want to mess up anything such as injectors, etc................

While low boost 5 will definitely make more smoke I haven't seen much change in 1/4 mile times. I have noticed that the engine oil will get sooted up (dirty)quicker.

I run the Pred 40 tune and the Edge on different tunes but mostly level 3. I set the low boost on 5. I haven't noticed any negative effects at this point. I've been running this for about 7K miles. What "a bear" said about the added soot in the oil will be less severe if you use the finger stick and egr blocker plate. I just had my oil analysis done and I had virtually no soot in the oil (<.1)
