I looked through there and didn't see any pics.
Now, this is only if people are getting a P0191 that they would check for this correct?

Without removing the race valve, how can you tell? I can't even see mine to begin with and just by looking at them, they appear the same from the outside.

I think when they use th eTech 2 on it they messure the amount of fuel being returned and there is no reading since this mod is done.

I figure if I boost power Its my fault and would never warranty a claim for breakdown as I suppose most of us feel on this site. Gotta pay to play.
