these are marginal for a completely stock truck, even the best ddrp's. and i have seen several brand new ddrp's weak out of the box, in fact pulling down to 2psi @ wot on a stock truck.
no way to adj fp. and even if you have a good ddrp you will be low fp running a comp.
step up to the better fass imo
