Car just hit 40k miles. Been tuned since 30k. Pretty much everytime I give the old girl a little taste of wot everyone tells me it dumps out the black smoke lol I know it's normal for a lnf but how much is too much? I think my a/f is at 12.3 at wot and 14.5 cruising. I don't really give it too much maybe one or two good pulls a week so i figure that has something to do with it also.


Edit
I figure my choice of a basically straight 3" exhaust doesn't help the fact either lol

 

Vince usually tunes cars a little on the rich side all cars on trifecta i know of all have black smoke. Im at around 13 flat at WOT and im hp tuned.

 

Duramax swap maybe?

 

Hmm nown that you mention that I have heard that before.


Haha i wish

 

What these cars produce even modded is no where near rolling coal

 

.yeah I know. I've been around many diesels.
