I always see these psd trucks blowing black smoke.Mine doesn't do it.I was wondering if it is because I still have the muffler on my truck.I have the banks pipe .If I remove the muffler will I gain any HP or MPG? Any help would be greatly appreciated...

Yes sir..sorry my mistake...LOL still a little touchy about the A hole at the inspection station..lol
i fixed your post for ya Barry
and no muffler makes more power, cause there is less restriction, so the turbo can spool up faster.
but no muffler also makes for ticked off neighbors when you fire it up in the early morning hours.
for the puff of smoke, you will need to "juice the pump" a bit.

You'll need to "chip" it. I had a SCMT on mine, and the black smoke poured out of it. I took the cat and muffler of of mine, I don't know if it helped on the power...I took it off the same day I bought it.
