The really cheap part was the interest. The most popular (best performing) tuner is $600. Hardly worth it for just a timing bump.
I'lll probably go with the ROKKTECH Sensor mod (relatively cheap) to keep the timing slightly advanced.
EFILive promises that my year/model of truck/engine will be available for their in-depth, comprehensive abilities in the near future. That is, if someone can be found to write a longest-lived, highest economy engine tune.
Thanks for the reply.
