Subsequent tunes at ASG are much cheaper than your first tune from my experience. My first was somewhere around the $1200 mark, my second with a good amount of changes under the hood and adding e85 was around $500.

The first tune can be a little bit to swallow, but if you stick with the same tuner it should be cheaper after all the licences (if any) are paid for and initial work is done.
