you'll have to excuse my lack of knowledge with diesels. But what is a surge problem and what is a aftermarket wheel? Also it didn't do it with the factory air box but the day after i installed it (AFE box) we went camping and it was makeing that noise the power is still there and my gas milage shot up by 2.5 gpm with the aftermarket air box but that dang noise! I don't know if I'm explaining the noise right, its definately a suction sounding noise. Is it possible that I have a big air box and filter and no other upgrades and that im getting too much air? Thats why I was going for the 4" exhaust upgade as well? The parts place i bought the afe from said I should do both at the same time I wonder if that is why? Should i move this thread over to powerstroke problems?
Thanks Tim
