What programmer for mileage

[Roccorace]

I know this has been done a thousand times but...

I have a 5.3l 2005 Yukon and I want to squeeze some more power and mileage out of it. I have a corsa cat-back on it and I am putting a CAI on it so I would like to compliment it with a decent mapper. I don't know if you guys all share programs or if one of the out of the box tuners works pretty well. I would like the ability to switch it out from time to time so I dont want to pay a shop to tune it.

I have tuned my 06 kawi with a commander and my turbo race vw with a split second so I am not new to the idea I am just new to the Yukon.

I am a newb here so thank in advance for the help (and possible flames).

Well since you want the ability to switch back and forth, I'm a fan of superchips for a handheld. I have compared them to hypertech and like how they achieve their tunes. There is also diablo sport and recently I came across F.A.S.T. They claim to be able to make changes for cams which, I would like to see the file, and how they do it. Good luck!

any reason why you would swap tune in, then tune back out?
