I went a different direction and bought a F.I.R.S.T. TPI system. Complete set up was a bit less than FAST and utilizes a factory GM computer. Check out my build thread for more details. Here's a link to FIRST TPI.https://www.firstfuelinjection.com

I've been running the set up since March and now have a little over 5,000 miles of trouble free operation. The truck is running a new ZZ4, 700R4, and return a shade over 16mpg hwy. Just changed over to Mobil 1, and I'm hoping for a bit of improvement in gas milage.
