Ive got a Blitz Dual SBC sitting in my gagrage, was in the car for a while and then got an after martket ecu which will eventually control my boost and the next tune.
Good unit, holds boost well, occasional spike, fairly easy to use.
In re to the question (sorry for whoring) when i had my boost controller i was running 14psi all day, now am running ~12psi.
