What kind of warranty do you have ? I pick up the endurance "supreme" bullshit for my car and if something goes wrong with a part ex your turbo . The dealer will blame ur aftermarket dp. I'm in the same boat. When you add jb4 or Cobb tuner the dealer already knows. My friend works in the dealer and he sees it all the time .

Dude, this may be stating the obvious but you do not have an "undetectable" build since you have already replaced the wheels. Everyone is going to wonder what other mods you have done. I also wanted a stealth build but had to make some compromises, and new wheels was one of them. Since you just got this car a few days ago, my best advice to you is to keep reading (you are using the search button I hope) and come up with a mod plan before diving in. I can't say anything about the JB4, but I really like my Cobb pro tune. I've spent a lot of money on hardware but the biggest single boost I've had so far was from the pro tune. Also, I modded the suspension on my car before I started in on the engine. Save some money for suspension mods, if you're not yet feeling the weaknesses of the stock suspension you surely will when you are making more power.

And definitely look into that E85. California gasoline sucks. What part of CA do you live in? If you can find a good indy shop and a mod-friendly dealership/service advisor you might not need to worry about the warranty as much as you think.
