Im running a intercooled t3/t4 turbo on a h22a and im having problems going into boost. Ive already done the basic trouble shooting(checking for leaks, rechecking my vacume sources etc.) what else could cause the motor not to go into boost. The blow off valve releases like its supposed to but its not as powerful as it should be. Im running a Tial Blow off Valve, Tial Waste gate, and FMU. Any other things I should Check?

 

Check your timing belt to make sure that you aren't off a tooth and timing is retarded or something.

Exhaust will be very hot at idle, if ignition timing is retarded.
