I am a new owner of 92 Typhoon. Has anyone experienced the problems of lack of power when engine is warm? When it's cold it runs great up to 15psi. When it warms up lucky to get 10psi. It's stock and reading off autometer guage. No codes. Have done plugs,wires,cap,rotor,o2,fuel filter,adj tps,adj tv cable. Could the turbo be going out? Or the wastegate? HELP!
