So, I was throwing some codes in my 2nd gen supercharged 4.0. Knowing a friend who just punched holes in a piston in his V8 Tundra - 2x in less than a couple of months, I was getting nervous. The codes that I was throwing were lean codes. I was a bit nervous.

I first thought it may be that stupied K&N oil type air filter in a MAF sensored vehicle. So I cleaned the snot out of the MAF. I had to go to Baja for 10 days so I bought a new MAF sensor thinking that may cure my issue along...
