Yea yea, I know it's a newbie question, but I just don't know. lol. My friend told me that when my turbo starts to spool up in 1st, he saw a bunch of black smoke spurting out of my stock exhaust. I'm pretty sure that's because I run lean. I also only get like 16-19mpg. What do I need to check? What do I need to set it so I'm not running so lean @ WOT? Also, if this has been brought up, tell me what terms to look up because I tried and couldn't find it. lol. Thanks.
