Boosted 5.3
#2
Not sure what you call high boost but I was running a Vic JR. and Tall Elbow and would initially spike to 30lbs of boost and then stay at 25lbs. Have it turned down to 15lbs now and in the process of putting a Pro Flo on. Everything is done but have to redo my intake pipe so haven't had a chance to see how well it does. A vic Jr and tall elbow had no issues though.
