Message	i put one ashpec ecu in my car and it boosts 14psi. i switch it to another one and it boosts 9psi. i can go back and forth and same results. (wastegastes are at 14) a friend of mine has a z and his does the same with a 2 z1 computers. all chips are for same programs. Can the ecu change your boost? I thought of it more as physics and whatever the wastegate spring was it would open at regardless. No boost controllers, no safty boost solenoids, Just wastegates routed into the boost hoses where they should be. BTW this isnt a problem with my car, obviously i know which chip to use. this is just a general question.
