New parts fo engine??

I was wondering... if I get a new chip for my car that boosts the amount of gas/air to my engine for turbo, do i have to get new/better parts for the engine? I really do not want to kill my car but I do want to make a bit faster.

One word, V8. Haha JK. Actually, just google for it. www.andysautosport.com is a good place to start though, and there are a lot of other places too.

LOL.. I was seriously going to be like WTF?!? that was a good one
