Mattio said:I recently installed a BFMIC and CAI, now the car boosts less!! I used to spike 18 than fall off to 16 or so with only the spring mod. After the install, car dosent spike at all! Just climbs to 15 and falls off to about 12... WTF!!?? Already boost leak tested, nothing found... what is wrong?
leak test it again.....do a leak down test from 20psi to 0. make sure it takes longer than 1:30 to leak down fully.
