you wont notice a difference unless u get a cai..bov didnt make a noticable difference on the way my car pulls.didnt notice spool because i ran vta untill i got my cai...smoknspeed3 said:What's something like this cost? I'm afraid to ask. I notice a small rang where the car pulls like crazy, I would guess it's about 3k rpm. Before that it's pretty weak it mellows in the higher RPM's but still pulls also in between shifts it bogs a little, will this fix the problem? I'm guessing it's just the time the turbo takes to spool.
