Autocal or inperson are your options, due to the computers used in your vehicle.
Same above options for your vehicle.

Typical gains are 10-15HP, but biggest things are much improved throttle response and better shift patterns.

That's interesting, as every Tahoe I test drove was a little "slow" to respond to the throttle. Mine is no different. So...the result will be a more responsive throttle, but not so fast that we will be eating too much fuel? :)

Depends where you driving, if every day you seat in traffic hours,forget about that. Mpg is going down.
