I have been working on a TBI install on my 305 SBC. I had a Q-jet that ran awesome, but wanted better off-angle running. Since my engine is nowhere near stock I needed to customize the tune. Not a cheap endeavor, but has turned out to be well worth it. With the Q-Jet I was getting 12 MPG on the highway. I am not done with my TBI tune, but logged a true 15.6 MPG on a highway test run. Next up is to enable "highway lean cruise". It's supposed to be good for an additional 10 - 20% gain.

Go TBI!
