need help well my boost is set on 20psi but when i went home it was on 15 i doubled checked everything from the intake throttle down to the intercooler. the mods that i have is HKS BOV, your custom flash and a hallman boost controller.. then i added a HKS intake too.. today i replaced the BOV with the stock now it went down to 11 psi.. men whats wrong with my car.. i havent reflashed my ecu with you yet with the new mod i got.. tha intake... could it be with the ecu? i dont know please help me out.. or anyone please help me out.. thanks

 

Was it working before? If it was boosting 20 psi before and now can't get above 15, I would check all your wastegate and bov vacuum hoses. Make sure there are no breaks in them. There was also an interesting way to check for boost leaks that somebody gave. Use a radiator hose with a PVC pipe end cap. Drill a hole in the cap and put a tire stem in it. Put this on the intake of your turbo and pump away and listen for leaks. Just dont go above normal boost level (no higher than 24 psi or so) you can use a tire gauge to check. I thought it was a neat idea and I will probably eventually fabricate it.

 

alright thanks.. but we double checked all the lines there good.. but i will still try that i dea you got.. just to make sure.. imma try it this weekend dont have time for the week to busy at work.. thanks if anyone got anymore ideas please feel free i would greatly appreciate it

 

Have you tried adjusting your MBC? and check vacuum lines to MBC also.

 

yup did the same thing too...

 

What were your exact mods when I custom tuned your car ?

You should have come by for a re-tune this weekend while I was in la

 

check the boost gauge hose connection etc

 

i was almost stock except for the HKS BOV w/ recirc..but now i have a an HKS RS intake now.. i couldnt make it this weekend i am so busy this month..

i checked all the hoses too there in good condition.. not cracks or holes.. i think i bring my car to the dealer and have them check it out.. is this a good idea?

 

It is NOT a good idea to swap to the HKS intake when you are flashed for the stock intake - this may be part of your problem

 

oh ok so i need to mail my ecu to you to flash it?
