I’ve seen E50 cars dyno lower whp but more tq then E85’s.For the most part Mikey doesn’t sell parts. So if he showed up for tuning in person he should’ve purchased and installed the kit prior to tuning or should have done a little more due diligence. I tuned with Mikey in person and wasn’t aware of what was needed for flex and specifically asked what the options are. He offered map switching or buy a flex fuel kit from a vendor and tune for flex fuel at a later date.
Another tidbit… it was mentioned to me that the straight e50 tune cars seems to dyno higher than the flex fuel cars. I’ve heard other ppl say otherwise but mixing isn’t a big deal to me.
