In regards to the power increases, that’s running E85 fuel. Power gains for 91 octane are much more modest. Having said that, I bought said tuner and it is noticeably peppier in everyday driving. I have no plans to run 93, e30, or e85 to really take advantage of the tuner.

thinking of buying the cat 6 from holley, im wondering how it does as a daily driver? do you switch it on and off as needed or is there a stock setting or just run it like normal? and by normal i mean cat 6 or jb4 installed at whatever performance setting? any issues with it? i know when i put my truck in sport mode my truck is a little wanky on take offs, shifting is hard and noticeable, is it worse with tuner?

So once you set the map/tune it stays in there until you change it. That’s assuming you don’t disconnect the tuner itself.
I keep it in map 1 and don’t notice any hard shifting or anything. Just spools up a little faster than normal.
I’ve run map 2 a couple times and didn’t notice any hard shifts there either but my experience was limited.
I don’t know how many people would run map 3 or 4 full time since you’re supposed to run E30/E85 on those tunes.

I’ve not really run the truck in Sport mode but I’ll give it a shot tomorrow.
