Chips

I need a Chip that won't cost alot of money but will still make a big difference on the preformence. Is this possible... I am willing to spend up to 100.00 dollers. Just cant afford 200 to 300 doller chips. I did happen to see some one on ebay it's The Redline power chip is this any good ?? what is good or bad for chips can someone help please...

Diablo and Superchips are really the only decent ones for the zx2. sorry man, but if you want a good one you gotta spend the cash.
