OH MY GOSH! I just FINALLY install my AEM UEGO Wideband today. And I am seeing my Air/Fuel are ALL OVER the place! I didn't realized that it would that BAD. I need VERY good tune BAD! I did put O2 Bung right in between Header and before Flex Pipe that go down to Catted. It's REALLY BAD!

 

welcome to a canned tune. lol. we all end up doin remote or own tuning with HP or trifecta for this reason

 

Yeah, I am planning to call Local Tuner tomorrow and see when he can tune my car.
