I have been pushing 400hp with flexfuel that has been on average of 74% for over a year and before that running 93 for a year. It's important not to tune for to much low end with factory rods. My boost controller will not allow more than 8psi under 4500rpms for good reason. Just set your maps boost control duty cycle for rpm/duty. No knock at all. I beat the shit out of her everyday, as she's my daily driver. Minus to everything is 3k oil changes and 10k miles I need new rear tires.
I have 27k miles boosted and loving it, no problems at all.
