Look guys, I'm not sure there were ever maps out for the 17/22 but the "standard accepted" boost level on that hybrid is "around" 25 psi from what I've heard. Jeff (RC) said you can run them up around 28 through the mid range of the power band as well. Will it shorten life? Probably. Are there dozens of people on this club who run 25 psi or higher on there 17/22's? Absolutely. Are they blowing up left and right? Nope...
