99 Tahoe Programmer for MPG??

[jayharrell]

Well i love my 69, but its time to get the wife a little bigger ride to go along with it. I'm looking at some used 99 tahoes for around 3k. I hear from buddies that they get around 18mpg.

Question: Has anyone ever used a programmer to get some better MPG?

When i get one in the next month or so, i'm thinking a cold air intake and reprogram it. Maybe some dual exaust too. That should get the MPG up.

But i've seen sooo many different brands and types on jegs and summit its hard to pick a programmer out of the dark. So i'm looking to see if anyone has used one, what kinda improvment you might of gotten and such.
