ok I have not changed mine because I have the GMS1 and dont want to put it back to stock and have gm reflash me. But I have cleaned it everytime I do that its fixed for a few weeks then 5psi. so I was thinking there must be a lot of oil in my intake manifold and charge pipes and would it help to clean them? before I try this I wanted to know if anyone else has done this.

thanks,

 

GMS1 is a upgraded MAP sensor. Not MAF sensor. I am currently going through the same battle.

 

ok yea I clean the upper and lower everytime I get the problem I can c oil on both

 

The MAF sensor is in the air intake. The sensor in the charge pipe is a TMAP I believe.

 

gotcha thanks for clearing that up lol....anyways do you guys think this will fix my problem?

 

clean maf, check for boost leaks. Getting any codes?

 

no codes I will also get a flutter when I let off when this happens.

 

have you checked for a boost leak check ic pipe connections

 

yes, although I have a CS intercooler I have been told then are more likely to crack....should i make a boost tester
