Just wondering what you guys are boosting? I'm around 2200 feet and seeing only 16lbs of boost in 3rd gear on a 2.6" Just wondering if that's normal or not.

 

didnt you start a thread like last week asking the same question ?? and everyone said you were ok if i remember

 

Your not even that high of elevation lmao!!!

You should have posted this in the alberta section. Better to get responses from guys in the same area.....


Your a lower elevation than edmonton and calgary.

 

The last thread was asking what your boost in general was. Seems like I have the lowest boost of all the 2.6 or 2.5" people. Just making sure here.

 

that seems low to me.

im at about 5,200ft (and sometimes 7,000ft), and i see 15lbs of boost with a 2.8"

 

I dunno man, Edmonton is 2372ft so it's not that much difference.

 

me too im hitting 17.5 weak

 

OK so there must be something wrong with my car then right? Does anyone know how I can check this out? I ran a 2.8" for a while at sealevel and saw over 16lbs of boost there with the 2.8"

 

when i had my 3.0 i was hitting like 14.5 -15.0 now im hitting 17.5 with a 2,6 , when my car runs that is , ****** piece of **** cobalt has been ****** up on me as of late

 

i am at 5700 feet, and boosting around 17.

 

So something is wrong for sure. I'm actually lucky for my boost to hit 16lbs, it just barely creeps up to 16lbs mostly high 15s. My cars got 35000kms on it right now. What can I check out to see why my boost is so low?

 

vacuum lines, and your bypass valve i would start there i guess not for sure though

 

All my vacuum lines are ok, I checked them. Not sure how to check the bypass vale though. Had the SC off the car tons and never really looked at the bypass valve.

 

im a little over 4k and im seeing 16 psi.. But my exhaust is too free flowing so that is a contributor

 

I've got a CAI, header and 3" piping and a highflow cat, think that's why I'm only seeing 16psi on a 2.6"

 

Really dumb question and I'm sure you have checked, but is your filter clean?

 

I think my car overboosts

I sometimes, very rarely only on super cold nights, see almost 19lbs. And yea, I have a 2.8!

 

Ya, I cleaned it over the winter when the car was all apart in storage. I've only put 300 kms on it since then.

 

I am at 4400ft and with a Stage 2 I am only getting 12.5. Isnt that low? I just got it installed in january so is there a newer tune for this?

 

Is your rev limiter 7000rpm or 6500rpm?

 

Do not know. Just wondering if a newer tune has come out since Jan 07.

 

I don't know for sure. But check to see if you have a 6500rpm or 7000rpm rev limiter. If it's 6500rpm then that explains your only seeing 12.5lbs of boost, meaning GM didn't flash your car right.

 

Hell, I think I'm hitting 15-16 with stage II. I'm no way near high eve. though.

 

Hmmm. This sure is disapointing

 

You will figure it out. Just give it time. Would be nice if you could find another SS/SC in your area with the same type of mods or another SS/SC at all for that matter. Good luck man.
