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?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.
