How much boost??

How much boost are you guys seeing at idle? And what is the max boost?

Idle ----> 1 1/2 to 2 lbs
MaX ----> 26/27

Typically 0 to 0.5 lb. Depends upon whether or not I'm running AC and any other accessories.

Max boost stock was 24.5 lb.

Are you guys making boost @ idle ?
I don't show anything until I hit around 1300 - 1400 RPM's and that's with a load on the engine .
Am I missing something ??????

urs is an 03? mine is and i see 2-3 at idle. 3 if i just come to a stop, then it comes down as it cools.

my max is near 33 just driving. with a good load on a hill with the water on, the boost can touch on the 40psi mark


oops, i just noticed these were all 03's in this thread....... shoots that theory........ haaarrumph

Just curious, do you have exhaust mods? How about Colorado?

What about the rest of you? I would like to see boost readings at idle with exhaust mods and no mods.

Hmm...thats wierd, I have never seen boost at idle...

For some reason, mine seems to be gaining .2 to .3 lbs peak per day now...and the turbo keeps getting progressively louder. I doubt it will last much longer No kidding...the turbo noise is getting really, really obnoxious, with no signs of letting off- it has never done this before.

Its a straight through muffler, thats not it...it never made this much noise even with a straight pipe. I'm %99 sure the compressor shaft bearings are dying- it makes some wierd vibrations periodically, that are definately coming from the turbo.

Get your butt on yahoo...
