Boost leak somewhere. Need help.

[born4music04]

For some reason, my boost isn't coming on till about 4000rpms and finally hits full boost at about 5100rpms. I looked at all the intercooler piping and such and couldn't find any leaks. I made sure everything was tight but may have missed something. Any suggestions for where to look or some other ideas? Thanks for the help.

Build a boost leak tester. Details are on vfaq somewhere.

Any other suggestions?

im not sure, but if you had a leak i dunno if you would even make full boost maybe if it was just a small one or something, just sounds like something other then a leak to me but i have been wrong many times before on this board soooo......i dunno.

Its going to be very difficult to track down the leaks if you don't use a Leak Tester. You can build one for less then $5.00. Small air leaks are near impossible to find without pressurizing the intake tract.
