Default questions about the hypertech piggy back pcm and k&n on my car

my car came with the k&n cai and hypertech piggyback pcm. i cant find any info on what the hypertech actually does or numbers and all ive heard is it sucks, i notice its not available for a 94-95 lt1 any more so their site has no info.does anyone know or have anything nice to say about it?
im sure the k&n helps but how much really?

i used hypertech a long time ago in the 90's and i was pissed i paid 400 for nothing. Thats all i have to say about them. But custom tunes are bad *** on stock cars for the most part.

no difference at all, maybe slower without it, gas mileage seems better with it. it defiantly not hurting the cars performance nor does it seem to help.

yeah i want to do a custom tune to the car just to see how much i can squeeze out of it. i want to learn how to do that stuff myself since i have a few projects where i need to be able to tune a car and from what ive seem the so called tuners in my area are not good and want alot for shitty work. at the same time im not tryn to play with megasquirt. i am thinkn ls1 coil conversion.
so is the k&n really good for 15hp?

Its not a piggy back pcm, just a programmer.
