I see 17.5... stock

 

we see better gas mileage than u..

 

 

I took all boost limitations, tq management, and throttle limits out with hptuners

 

Okay... wait a minute... back on topic here.

If you have time to even look at the boost gauge in 1st gear something's up. I have no idea how much boost I get in 1st b/c my eyes are always glued to the tach if I punch it in 1st.

The SS/SC will hit 12psi stock at around 6000 RPM in 2nd and 3rd... it takes a little time to creep up there from 10.

If you have less than oh say 1000 miles on the car you are gonna be limited in boost until the car "breaks in" anyways. I really wouldn't go back to the dealer and be nitpicking over it... everything sounds fine... god I hate the thought of some numbskull tech rummaging around under my hood or going out and thrashing my car on a "test drive" chasing after a ghost problem.

 

X2..

 

how many miles do you have on the car

 

so whats gm stage 2 should be at 15-20psi

 

GM Stage 2 is 15psi.

Every car is different... and pressure will change some with altitude... but that's a nice round figure that you should be close to.

Perosnally I get a little past 15PSI when I really open her up... maybe 15.5.

 

i just went out and i'm seeing 70-80kpa....i dont have a PSI,,,,,,its says kpa

 

a freind looks for me lol
theres no way i could look

 

i get 12 in 1st gear,and every other gear when i pass 4k i see 12.5,13 psi..i got 21k on my car

 

I got 3500 miles ruffly on my car so i should be well past the break in period

 

so how much are u seeing...with those mods in ur sig u should be around 13-14psi..maybe little more

 

just over 80kpa is 12psi

 

15 psi...Stage 2

 

last time i data logged I was at 10.88 psi I havent checked my psi after the downpipe install and the k&n filter. but on my boost gauge its barely past 10psi....... to me lower psi is fine with me cause to me that means less restriction cause psi is a measurement of restriction
