k1996z28

ok I'm new here so bare with me i have a 96 z28 that I've owned for a year now and haven't done any upgrades to it since i got it just regular maintenance. So I'm wanting to put longtube headers on it and delete the cats, egr, and AIR and I'm wanting to know is what is a good programmer to get rid of the cel light and will let the engine run right. I'm not planning on modding it any further than this i have heard of the mail order tunes but dont think thats what I want to do unless it is necessary.
Thanks!

Not familiar with any hand-helds for the LT1. The JET Dynamic Spectrum Tuner (DST) might do it, but it's expensive. A mail order tune, particularly one that's just eliminating codes and tweaking the stock tune for the typical extra 10-15HP is going to cost less.

You will gain very little by eliminating the cats, EGR and AIR. The dual cats on the OBD-2 cars are fairly efficient. EGR does not operate at idle, above 3,500RPM or at wide open throttle, the electric AIR pump only runs for a couple minutes at startup to heat the cats, then shuts down - no effect on performance.
