I installed my DD1's and PS boost module about 3 weeks ago. It is wonderful and I now accelerate on the hills while I'm towing about 7,000 lbs. I noticed that it smokes a little more when I really get on the go pedal. I can see what looks like black smoke when I'm accelerating hard. I did notice the same thing when my motor was stock, but not very often.
Is this normal? Should I be worried? What type of fuel injection cleaner/injection pump lubricant do you use?
Thanks in advance,
Charles
