Driving the SS all day guess what on full throttle not once but all day my car was just hitting 15psi according to the gauge, now I know the gauge might not be accurate but it has never gone past 12.5-13 before and today the damn thing hits 15 and then slowly as it approaches redline sinks down...WTF?!?!?!? Not that I am complaining, but I just got the car from the dealer Thursday and now its doing this? they were trying to figure some shiznit out maybe the flashed stg 1 into the pcm(ya right)

Anyone have this happen? :twothumbs

No idea, not to alarm you, but a few members had increased boost because of faulty cat which was creating backpressure.

if you want it to stay at 15 psi to redline, i think you have to do the boost bypass mod

Well i know that right after i installed my CAI. it was below 30 degrees and i was getting 15 psi. Was it really cold that day?

ya it was cold all day...and doing it all day..... :cssNET:

nice... watch out for the cat problem tho....

After I put my cai I got up to about 14 boost. I figured it was that. I don't think it is the cat because I can't smell sulfer. But it don't matter I just got my Magnaflow catback w/ high flow cat. :twothumbs

if the weather was decent then you could see more psi

but if its doing it all the time i would bring it in to get checked out

cold weather = more boost

I hit around 15 Psi all the time. I am in Ontario though and it is colder than a witches titty up here.
