Default odd issue

Ok so i came across a very strange problem. My car seems to show boost 15psi but it almost feels like it kicks on then die's off again. But when it does this the boost is still reading 15psi. So im not sure what going on hear any ideas?

sounds like something is not right and the engine is pulling timing. Could be as simple as bad gas or a dying maf

No cel yet. Im almost certain its not a boost leak. I will try unplugging the maf on the way home from work. How far can you drive with it unplugged. I know your car will go into open loop eventually but is it ok to drive with it unplugged for about 20 minutes or so? Ill go aheand and check the plugs today too.

i thought my maf was bad and ran the car w/o the maf for a few months. Found out when my engine was pulled that the bolt holdingthe tip on was missing and it wasnt attached. D'oh!!
