honestly the blow off valve can be filtered but because it releasing extreme amounts of air nothing is going to be sucked in at all that and its only open for a split second... and when on the rocks, there is just next to no turbo lag what so ever.. and the boost comes in very smooth.. its not violent at all. as for gearing, thats why we are playing with the diffs the trooper has a factory 2.13 gear and i think it would do A LOT better with a 3.55 or 3.73, yes you will lose top end speed but down here its all about the mud in which case we dont see speeds over 25 mph very often..
