Funny, the day after I got my chip installed (and I already had an intake), I went up against a 97-01 Prelude on the highway. We were dead even.
Coincidentally, last night on the way home from the meet at BMW Autohaus, I got in a battle with a 92-96 Prelude, an SR (160hp)model. I can see his exhaust and hear his intake, but I'm not sure what else he had. Anyways, I was pulling on him slightly every run we made.
Oh, and the chip made a world of a difference on my car. Whenever I have doubts I put it back to stock for a week, and that is always a rude awakening.
