i get 41 when i let the pump prime the system, when i kill the key, its bleeds down slowly till about 20, takes a while to get there though but it will bleed off like 30 seconds after i kill it. when the car idles i get roughly 35psi, if i give it gas and hold it at any rpm, it shoots up to 40 then goes back down to 35ish. i dont have a gauge i can use to see what it is at wot or driving, maybee this weekend ill pick one up. how does this sound so far, the car seemed down on power, backfired today when i gave it maybee 3/4 throttle from a stop, and when its floored it feels like it gains then looses then gains the looses, kinda like a choppy dyno graph but i can feel it. car is an all stock 93 accept for a delteq system. thanks -dave
