Alright for starters I have the entire intake system all bolted together and everything.....All Brand New gaskets all around and everything.....
Intake mods
SBR Stainless J pipe
SBR RACE FMIC
Tial BOV
GM MAF
Magnus SMIM

Put the boost leak tester on the turbo, pressurized the system....went up to 5 psi...stopped and then I heard a leak coming from the gm maf WTF

Looked all around and felt all around it to see if I could feel any air coming out....couldn't find the source....quiet confusing...

I have the 4-ply silicone as far up on the gm maf as possible but yet it still leaks....

Anyone please chime in with a hint or a clue thx.....I'll try to figured it out more this weekend when I have time
 
Get yourself a spray bottle with a soap and water mixture. Then do the boost leak again, but while applying pressure to the system, squirt the bottle near any of the spots that you hear a noise. Spray all of your couplers, around the Tb area, on the BISS, and any of your vacuum hoses.
 
If you take the 4 screws out of the gm maf and pull the metal ends you'll find 2 large rubber o-rings. Clean those up and apply silicone to them and re-assemble. Should fix that boost leak. :thumb:
