BOOST

[JDSTROKER]

WHAT KIND OF BOOST SHOULD I BE SEEING? AT FULL LOAD I HAVE NEVER SAW MORE THAN 21. SOUNDS LIKE IT KEEPS TRYING TO GET UNDER TURBO CHARGER. SINCE INSTALLING COLD AIR INTAKE IT HAS STARTED THIS. TURBO HISSES REALLY LOUD AND BARKS ALOT. DO I NEED TO UPGRADE MY COMPRESSOR WHEEL?

Installing one of those shock collars may help with the barking problem .

Putting the cold air intake probably just made you able to hear the symptoms your describing and not actually causing them. WHat do you mean by get under turbo charger?

Have you ever been to a tractor pull and when they get to the end and under heavy load the turbo starts chirping? It like there is more exhaust pressure than intake pressure causing the compressor wheel the be pushed instead of turned.

It's just surge (if it's doing it under load) or the air coming back out if you just let off the throttle. Normal.

With no tuner... I can rarely get my turbo to spool to 16lbs.

Ok so check for exhaust leaks, boost leaks, or a sticking EBPV. Also, how are you reading boost?
