I know my evo9 was not flex fuel and had to upgrade injecters and adjust tune to get scaling and afr correct for e85. E85 is like steroids on evos and for silverado i have only noticed minor gain so far witout a tune. For the silverado since mine is flex fuel i believe it adjust the afr for e85. For non flex truck, i would strongly recommend tune for it. I am new to silverado so i don not know if your afr will automatically adjust to e85 without a tune. I wont gamble with that unless i knew for sure.

I went with black bear because lew did not offer e85 tune and that's what I run 95 percent of the time. Black bear said he did not have any issue with e85 tuning. Did not even consider canned tune. My background drove evo9 for almost 10 years using e85 the last 6. Did Plenty of remote flashing with bigger injectors and evo scan plus ecu flash. Tried using that on truck with no luck. My only concern with disablew or bb was how do they fully tune AFR without a wide band scan? I guess I will find out once my auto cal arrives.
