Okay so the fifth month of my car is coming up and I am scheduled to go in for the mantinence and free oilchange and maybe rotation. Anyway Since they will be tinkering under my hood, do you think they will have issues with any of my aftermarket parts? I have the GFI installed and the TWM shortshifter installed as of now. Will they give me any junk about voiding my warranty or tell me to go put my OEM parts back on? Just wondering..thanks guys.
