Possible Boost Leak?

I just installed my vrsf intercooler and I am pretty certain I have a boost leak. The spool and dci sound way too loud.

I datalogged my car in 3rd gear and have the csv if needed.

What PID's do you need to see in order to rule I have a boost leak?

I got mine done at the shop today, drove 20 miles home car sounded like it was off, so low I love it. My idle is awesome, spool and dci sound awesome.

Are you reaching your boost targets? Is wgdc edging higher? If you have a boost leak the turbos will have to work harder to make the same amount of boost.

Is it that high for stage 1+? Very well may be. My freaking car only reaches 17 psi no matter what right now lol but you can log requested vs. actual boost and look at wgdc
