my program (that mike mentioned) is an old serial version of hptuners

I can edit any 2000 v8 car, but unfortunately they got smart and wanted more money so now when you buy their program (very pricey) you have to buy the license for whatever car and then credits for each vin I believe. I don't think you're really going to beat $150 unless you find someone with hptuners locally that's not looking for much (if any) profit

is it actually modified? or are you just trying to avoid replacing o2's?

mail order tune is another option and might at least get you a few hp if it's modified in addition to getting through inspection for the same price as the shop just tuning out sensors at least

there's also the spark plug non fouler trick, google it and see if you can trick the car to at least not throw the code. I don't hear of it much on fbody forums but it works on some cars with aftermarket or missing cats.
