hey guys ive tried to look for a person with the same problem as me all over the forums but cant seem to find someone. my problem is that I recive only about 1lb of boost, I have checked for boost leaks vacuum leaks, replaced my MAF and MAP sensors but my computer keeps throwing P0101 im not quite sure what else It could be it also threw one for Bank 1 sensor 2 02 sensor. the weird thing is that I used to be able to turn the car off while driving and turn it back on and get full boost again but I can no longer do that. I have consistently 1lb or lower. if yall have any ideas please share any help would be greatly appreciated.

running Turboxs cold air intake, HKS charge pipes and bov, Downpipes Exhaust and intercooler. not tuned.

 

Get your flamesuit on, since you're running a atmospheric BOV without a tune.

P0101 is almost always a boost leak. When you said you checked for leaks, what exactly did you mean? Visual checks do not work. See my sig.

 

myself and 2 others checked for the leak, around the intercooler pipeing and vacuum lines, while I slowly reved the engine they listened for any hissing, on top of doing a physical check we even felt down every hose for any possible hair line cracks.

 

Build a five dollar boost leak tester. I found a leak in the factory charge pipe and the brake booster fitting on the manifold. Use the tester, a spray bottle of soap and water, to find any leaks. You will see bubbles.

Also can spray starting fluid around while the car is running to see if the rpms pick up.

 

Listen to this man. It is impossible to see or hear the small boost leaks. Build a tester and find some compressed air. If you have a stock inter cooler, that is your most likely source for a crack. The cracks usually occur on the front face of the passenger-side end tank. You can't see that with the bumper cover on, so it is best to take that off when running a pressure test.

 

Also I'm assuming you have the block off plate on your bypass valve? could also be because your on a stock tune with a bov, the ecu is power controlled so you'll always be at 260hp, if you install a bov and increase the boost and the ecu sees higher than the 260hp (calculated) it records an error enough errors it can start to go to protect mode. Get a tune or remove the bov and build a proper boost least tester, reving the engine and listening for hissing is kinda like trying to hear a pin drop at a rock concert
