How lean does adding test pipes actually make the AFR mixture?

Test pipe,s will make you run leaner as with any increase in air flow should be countered with an increase in fuel flow.I asked my tuner,dave at functiontuned if i could just add my test pipes and wait a while before getting it tuned and he said it will run lean on the top end.I am waiting until next week to put these on and staying out of boost till i get tuned to be on the safe side.

I have test pipes on mine, Will. I had SGP retune it afterwards also. I have the 04[.5] so the CEL is on constantly 
SGP also told me that putting non-foulers on would mess up how they tune the car or the way the A/F reads or something... I have no idea [coulda been a line?]. Might be different for the 03's there also.
