Guys just had my 2006 Gt dyno'ed (446 to the wheels), during the process the techs noticed that my Fuel air ratio was unusally lean, so I had the gt500 pump installed. today I got the following code (fuelsystem too lean bank , OBD(?) system check not complete) after the gt500 pump install my air fuel was exactly where it was supposed to be. I have a procharger running with only tune adjustment being to the fuel pump after install. Any ideas

Fuel system too lean, bank 1 and/or 2 code usually means a vaccuum leak of some sort. As long as the A/F ratio is where it needs to be while in boost (low 12-high 11s) look for disconnected hoses.

Will do i am also going to clean my MAf when I get home, hopefully this will help. To clean the MAF i disconnet the negative battery lead, remove the sensor spray with maf clean replace and reconnect the battery correct?

I just opened the hood, where the heck is the MAF with a procheregr installed?
