If so, what chip should I go with without hurting my wallet.

Nope. If a chip really made a car run better, the manufacturer would have put it in themselves......































While some can indeed boost hp a little, it comes at the expense of mpg, amongst other things, including reliability and emissions.































Performance chips, male enhancement products, magic weight loss pills, all are wishful thinking.

The guys are right, most of the performance chips are for performance and allow more gas into the engine.

Nope, not a noticeable amount anyway. Besides a 91 Lexus isn't worth the effort.....
