I down shifted from 4th to 2nd and it just perfectly started to fly... WHen I did that the guage read 17lbs which stayed there untill I shifted. I just want to know if this normal.

 

Yes, anywhere between 15 and 18 without GMS1.

 

Sounds to me to be good boosting.

 

Thats what happens when the hammer is DOWN! lol

 

Thanks guys.. Is this car really reliable to power shifts on occassion because I have always beat on cars but because this one is new I am hesitant becasue I dont' want to blow the clutch as that is not covered under warranty.

 

I'm impressed. That's a lot more than I got stock.

 

my auto maxed out at about 17psi when i got on it....before the programmer
doesnt low elevation throw it off a bit?

 

NO clue that was the first time I have seen that much.. Maybe it was because it was from a downshift.. When I just floor it 15LBS is the norm..

 

You will see a little more from time to time depending on the weather, alt and load on the engine.

Once you get the GMPD upgrade kit most of us average 21-24 PSI.

 

Elevation, that special chill in the air, these critters will surprise you at times with bursts of incredible power, makes me smile

When it hits 29, hold on.
