decreased intercooler efficiency. Try this: Next time your car is "cold" remove the cooling fan relay and install a jumper wire in its place (use a good size wire gauge) jumping from pins 30 - 87. Look on the bottom of the relay for pin number reference. This will cause the fan to turn on, regardless if the engine is on or not. You will notice the boost remains higher for a longer period of time before heat soak takes over and lower boost returns. Your solution is to ensure that the airflow is optimum (aged cooling fins corroded and coated with road grime, insects etc...) through all of the cooling devices mounted in the front (a/c condenser, radiator, intercooler etc...) and don't forget the inside of the intercooler which is probably coated with oil residue. Better yet, with a stage 3 setup, a new intercooler is long overdue. HTH
