Overboost questions

[HeatInTheKitchen]

What's up guys im having some issues right now with my 08 STI. 1st and second gear I am over boosting by about 8-10lbs (not WOT about 5k RPMs) my target boost says 4 yet I will be hitting 12-14lbs. Then in 4th thru 6th I am not hitting my target boost by 2 lbs. Any body have any advice before I dive into my engine bay after work to check for leaks. Thanks

12-14 lbs pressure sounds like its your spring pressure. 4 psi might be too low. I currently have my WD cycle dissabled for breakin and i am still hitting 12 PSI. You could take a vaccume pump set it to pressure and connect it to your waste gate. Once you see the wastegate move, check how many psi it took to do this. This is your spring pressure...and should be your lowest pressure you can achieve for your turbo.
