I recently bought a 2007 base 987 with a TPC turbo installed stage 1, no sub-cooling. I have installed a pre-cool pipe where the intercooler should be and I want to know in which direction should I turn the control nut on the exhaust pressure dump valve to go from 4lbs of boost to about 6lbs. I'm not worried about wrecking the engine, as I want to replace it soon with a larger engine?
