Yes an operating temp drop means more of fuel is burning, IN the engine, more completely and rapidly. Of course assuming the previous rad. cap and t-stat were in decent shape. Did you see a power and MPG increase as well?

thanks for the info Milton indeed your Tahoe is a success story! :woohoo: Impressive gains!

Did you ever get any pic's of Ron's and your work, i.e. the Throttle body, did Ron take any video of it and you? Is yours the 5.3 Vortec, is it cable drive or drive by wire? I've Grooved just one Vortec, an '06 Chevy Avalanche 5.3 Vortec DBW. Got 50% gain on hiway, great power.

yes we do really miss Ron here, he always gave us great insight! I hope we get to hear from him, I can't contact him now.
