P050d & p0171

throwing both of these codes. Short term fuel trims for both banks go up to almost 30+ under part load and load. at idle its at 0 and looks okay.

any ideas what it could be?

Sounds like it has to do with the changes in the tune, like they leaned you out to much. Assuming this was not there when you had the email tune?

Correct it was not there prior to the dyno tune. Either the fuel pump is dying or the tune is off

I've gone thru many tunes, I really do not think it's the fuel pump. I'd get with the tuner and have him iron it out
