^maybe if youre doing bolt ons like headers, exhaust, intake...since some of those lean out the mixture, it might help..but seriously, no point getting a early ECU..

So there's no "matching" required? I ask because my last car was a saab 9-5 which had different models with different options so you had to find an ECU with the same transmission, etc as you had. I assume since the s2k has no real options like that, any ECU will work? Also, is there any reason one wouldn't want to do this to their 00-01?

Few hundred $$ for a few hp.. I guess it's up to the person spending the money.

There is no matching required. You could take any ECU from 00-05 and stick it in any other S2K. Some people take 02-03 ECUs and use them in their 04-05 so they can rev to 9k. There is no compatibility with the ECUs from 06-09 though because they added VSA, DBW, etc.
