eBay chips won't do anything, check YouTube videos about them, chips/remaps generally won't have much of an effect on a naturally aspirated car unless they've been modded a certain way like the M50 manifold mod on the 323/328s or major intake/exhaust mods.

Your money will be better spent on something else
