2017 Infiniti Q50 Premium 3.0t AWD
Well, I finally broke down, took off my JB4, and drove out to Houston to get my ecutek tune done by racebox. Come to find out, I have a pretty big boost issue that we think we narrowed down to the HKS Blowoff valves. On the dyno, once the boost hits 12psi, I lose all my boost. When the turbos spool up again back up to 12psi, it drops off again. Couldn't run a boost leak test while we were there because we didn't have the time. Having a hard time finding a shop near me to do it as well. Contacted ConceptZ where I bought the BOV from and they said to go get a boost leak test done, take videos and we'll send it all over to HKS. Guys at ConceptZ said out of the 300 BOVs they've shipped, only 2 have come back and when they put them on their cars to test them, everything was fine. I'm trying to figure out what the problem is or where the leak is exactly. We checked all the hoses and fittings and sprayed it with soapy water to check for leaks and came back empty-handed there. Anyone else ever have a similar issue? Everyone I've talked to so far acts like my car is the first one they've ever seen this issue on. I'm trying to figure it out ASAP so I can get the revision done so I don't have to run the base map.
