any body in or near the mongomery county area that has an auto with the GMPP turbo upgrade from dealer?

You're about the same distance as me from Newburgh, NY (175 miles).
I got mine done there at Barton Birks Chevrolet (about 1 mile from OCC).

They charged $200 for the install, soldered the connections like I asked them to, had me out by 10:30 AM and I've had no problems with it.

Not asking where to get it.. asking who has it... I have it already and just want to compare tunes .. there are 3 different hhr ss automatic tunes depending on VIN

I usually get 24 PSI but sometimes only 15, depending on RPM, speed, load, etc...

That's what im curious about iv never seen over 19... I would like to look at a tune via hp tuners

My wife has an 09 auto with the upgrade in MD. I see low 20's sometimes 25ish, but I don't really drive the car much.

Regardless of the specific attributes of the program application, you'll drive yourself crazy if you think that boost pressure will be consistent in any case. Temperature, air enthalpy, altitude and humidity are all variables that will affect atmospheric pressure and is magnified exponentially when further compressed. I run from 18 to 23psi when I feel like looking at the gauge, but can also predict where it might be depending upon the weather and if I an next to the Hudson River or up in the mountains (both of which are nearby).

Regardless the max iv ever seen is 19 in a high gear.. the average stage car sees between 20 and24

I don't 20-22 max, but mine isn't soldered, but it will be tues morn I'll let ya know if it makes more boost after that. I've been having the drop boost issue on ocasion if I squeeze the wires it works again so maybe this time they will listen to me and solder it.

all my wires were re-teminated no worries about connection
