the intercooler is a pretty decent size. it came with the kit from Turbo Specialties and it's front mount. i just replaced the vacuum line from the compressor housing to the actuator with a rubber vacuum hose and small hose clamps and now it peaked at 4psi @ 5800rpm one time on the way home from work. it was feeling loose and it was that clear plastic junk with zip ties holding it on. the impeller spins freely and gets plenty of oil. about 80psi under load because i installed a pressure sender right at the feed line so i know at all times. i also fixed a slight exhaust leak at the manifold to the heads. still not happy with the boost i'm making how do i check the actuator?
