    Does look like it...

    Can you run a log from 2000-6000rpm in 3rd without lifting? Also add commanded AFR so you can compare commanded vs actual.

    your AFR's are very rich (mid 10's)
    but it looks like your fuel pump is on the way out...
    your boost goes from 18 to 15 to 17 psi, which is very strange...

    Thank's guys, had pump internals are on the list to do soon.

    Fuel take had 1/4 tank left.

    As for the boost spike and then drop and lift again, i've got a feeling thats cause of the fmic which wasn't on the car when the tune was done.

    What parameter should I drop to gain CMD AFR?

    Or just run a different diagnostic set and do runs back to back?



    Are this posts suitable for this thread??? lol i'm not sure and feel bad for people that are looking at Versatune and are instead reading my posts lol
