Engine/Transmission (1998.5 - 2002) VA Boost and EGT #'s

[WardJ]

Can anyone offer their numbers for the van Aaken module. I would appreciate the info for comparison to my rig.



TIA

Easy 1350 but I cut back on throttle usually at 1250. Boost runs about 25lbs.

at heavy throttle. Wastegate elbow nut is reasonably tight. I'd like a 4" exhaust and 275's, but I need to decide on a lift pump upgrade first as I'm on my 3rd lift pump(87k miles).

1250 egt, 30-31 psi boost w/275 injectors

 

[ARoss]

1250 egt, 30-31 psi boost w/275 injectors

Under what conditions are these numbers. I have the same setup and pulling a grade, empty, I see 1000* and 30 lbs, when I step on it. Stock exhaust and intake. I do have an adjustable boost elbow.

I don't know why my truck signature doesn't come up when I post, but that is really with any load up to 17000 lbs on a 6% grade, 2000+ rpm. I have a bhaf and stock exhaust. That is not in the summer, though. I added the injectors this fall, so the ambient temps have been cooler. 275's didn't seem to raise the egt's any, but I gained another 4-5 lbs boot.
