Seafoam + DASC, should I do it?
 

I have always seafoamed all of the cars I have owned. I usually run it through the brake booster vaccum line into the intake manifold, but on the dasc ti, it would have to run through the supercharger. Is this going to harm anything with the charger, or is there another way to run it past the charger so the seafoam will not have to go through it? Every vehicle I have done this to, has run significantly better afterwords, and would really like to do it to the ti since it has almost 100k on it now. Let me know if anybody has done this. Thanks.

On the intake manifold there are two vacuum lines, one goes to the rising rate fuel pressure regulator, the other to your boost gauge (likely). Pull off one of those hoses and feed the Seafoam in that way. I would recommend using the line that goes to the boost gauge, not the fuel pressure regulator.

Hugo - There is your answer.

Dusten,

I read somewhere this stuff has 'acetone' in it.. If so, will that eat through the rubber fuel lines, if added to the gas tank as well?

I believe SeaFoam is just mineral spirits. It's safe for oil, and fuel.
