We got 6.8 with the rebuilt 8V92 last trip flat towing the F-350 (around 9K#) at about 67 mph. From Gallup to Kingman & back to Grants. A bit slower on the long slow grinds going east on I-40 out of Kingman. My temp gauge is a bit off but rather than risk engine damage I did a lot of 2nd & 3rd gear on hills. Based on S&S saying my temp gauge was 11-12 degrees off, I may have been down shifting to keep temps below +/- 195F instead of 205F. I have now invested in Silver Leaf. Got it today and will install it before next trip out. Based on past posts where folks have noticed a significant difference in Silver Leaf DDEC readings, did anyone replace their analog temp gauge to try & get a better match up of data? I tried the independent ground but was not able to get satisfactory results. Still bumping up +/- 5 degrees when I turned on head lights. Is there a check or calibration on the analog gauge or best to just replace?
