ive been trying to figure out what i want to do with my pump. i was thinking skat trak adjustable venturi mod with AAT tailcone. and mayb r&d 15mm extended steering nozzle with all of that? i dont know if the steering nozzle is worth it or if i should leave the venturi alone and go with the steering nozzle and AAT? is the skat trak venturi mod isnt considered a speed mod? or is it just to dial in the rpms? i figure with the venturi rings and AAT there a hell of alot of adjustment, bet there would be a descent gain in there somewhere. but then again if the adjustable venturi rings only give me 50 or so rpms of adjustment(either up or down) it doesnt seem like it would do too much. what do you guys think?
