Why are you yelling ? All CAPITAL expresses yelling. Can you tone it down a little please!!!!! Btw. WELCOME TO THE FORUM........couldn't help myself

 

Living in Edmonton area ask around they have a few great shops who can make that cat purr..

 

Cold air is thicker then warm air.

Altitude makes a difference also.

 

My opinion that's pretty low boost. But probably the norm for a strictly stock engine. Check for a cac leak and any leak around the rubber boots and turbo connections. What serial # is the engine? Mxs or nxs is what it will start with. The vav housings are the weak point on those engines. Make sure it has updated studs.

 

For the most part they are good engines. You need to have the ecm tuned by a private tuner and we won't talk about that due to the rules here on emissions. The fuel mileage will vary between 3.5 and 5.5 depends on what you hauling. Tuned will pick it up at least 1-1 1/2 mpg. Acerts have known actuators problems, broken studs, cracked jake housing, wiring harness issues just to name the most common. 40 psi on a twin is not enough in my eyes, my single turbo cat is doing 42. You could have a boost leak, boost sensor problem, or low fuel pressure or injector issue.
