I got my DP in today and on the 140 smoke tune I noticed a little smoke coming out by the front wheel. I looked and I figured it is coming from the down pipe or up pipes. I tightened the down pipe clamp some with a wrench and the up pipes don't appear to be leaking because there is no soot around the clamps. What should I do? Boost seems to be ok I can hit upwards of 25 psi

 

Check exhaust manifold for leaks.

 

find the leak first and address it. Leave it on 140 and smoke it up a bit so it will leave a tell tell trail wher it is leaking.

 

There is a smoke mode?

I think i'm in love.

 

Another area to check is the connection between the manifold and up-pipes. They tend to start leaking over time.

I wouldn't be worried about a little exhaust leak on the dp. I would classify it as normal as you can never seem to get those connections sealed up tight. However, if it's quite noticeable it needs attention.
