I've had my truck for about a month now. I've installed a boost gauge, and have a new pulley sitting on the counter waiting to go in, but I'm a little hesitant. I don't seem to be seeing as much boost as I should be. I'd like to see if something is wrong before moving ahead with that. (Or I'll just end up doing it next weekend anyway *shrug* but I did put it off this last weekend because of this). Here's what's happening...

When I first start up, I only see a max of about 2psi. Now I've only got a 12 mile commute to work, so many days that's all I see. If given a good chance to warm up, I'll see as high as 5psi. Isn't the stock boost supposed to be 6-7? Now I'm assuming the ECU is lowering the boost until the engine gets up to operating temperature, is this a good assumption to make? Does anyone know anything about this ecu that I dont?

Anyways, as it is, I'm rarely even seeing 5psi, but I'd like to know why most of the time it's just 2, I'm thinking it's the ecu, let me know what you think.
