There is a bit of a kick , not a lot but you can feel it. Driving is fine, the only thing is cold start , since it's e85 it cranks kinda weird. But other then that it's fine.
I probably should have explained it better, my fault. It is e85 with 68% percent ethanol. It actually did make power, I should have posted my baseline dyno pull. Also to note it was the same dyno and the weather is almost the same. So you were probably right that it made 460 hp but compared to...
Just to add, had mine for about 2 month and love it. No issues, I also had my gt350 dynode. To add my e85 percentage was 68%. I found a better pump with 72% but not sure it will make much difference.
