This worked alright!!! I was pressed for time and just managed to get the "flat response" change on the tune once I added the sensor and wired it up. I mounted it on the front of the block on a nice flat spot and just left the resonant sensor where it was and will deal with that when I swap the manifold with the marine manifold I have. I drove 850 miles day before yesterday and the mileage went from 20 to 23 without any other changes so I believe, without scanning yet, that this did the trick as far as my KS DTC is concerned and now I can start tuning/scanning!!

Thanks so very much for your time and help!

Good times!
