i pulled my old intake that is quite dirty and put a replacement on today. its is cleand and assembled correctly(i think), all vacuum lines are put on in the order in the manual. But the problem is now after runnin it a little bit i seem to have a flat spot from like 3000rpm -3800. it takes about 3-4 seconds for it to get through these rpms at full throttle. after those rpms it pulls like i have never felt the SHO pull b4. and also like my old intake i cant tell a difference of sound when my secondaries open, could my secondaris be poppin open early? under moderate acceleration thet dont open, but full throttle it seems like it bogs down... WHATs WRONG?
. the guy i got the intake from said taht the vacuum canister might be bad, and it was....
