Al,

I recent got rid of my stupid HKS VTA BOV, and put my stock BOV back on....Everything was fine until I looked down at my boost gauge and noticed that the boost was not holding at 19psi till red line...It would hit 19 and drop to 15-16psi fairly quickly...

Just so you can look up file in your computer, my name is Justin Hoffman and I did my flash with you on one of your first trips to Los Angeles (White Evo)

MODS:
HKS Turboback exhuast
Stock Cat
HKS 264 Cams
MBC

If you or anyone else has any ideas on how to fix this, please let me know.

Thanks,
Justin

 

Where you holding boost with the Hks BOV?
Did you check if you installed the stock one right? maybe stock is leaking.
check your hose clamps if their tight.
What MBC are you using? Maybe the spring inside is weakening and not holding boost anymore.

 

Stock BOVs palstic shotty valves leak for making them.

 

Agreed

Diagnostic quest is

1 - did boost hold with HKS BOV ?? If yes - get a new BOV - (I recomend Forge recirc bov) - problem fixed
