i guess it depends on the service guy there too..
i asked him before hand..that i am "thinking" of putting a TBE, MBC and induction box, and he said it should be fine... as long as the SES should not be on.. then i would be ok..
then when i asked him "could you get me this in writing".. he said no i am sorry.. this too much liability,, i even asked him to ask his service MGR, and his service MGR told me the same BS.. too much liability..

 

I wish that would be true! I would turn my car back to stock and throw on a 200 shot as my only mod. After every couple of pulls take it back to the dealership for a new motor

 

so i talked to my local dealership in costa mesa and they actually will tune your car there under warranty!! aint that some shiznit??! and they actually sell performance tuning parts and put them under warranty! and theyre not expensive too. pretty tuner friendly if you ask me.

 

i changed my shift knob and it voided my warranty. j/k heh.
