chevron, there's a shell station right by me, but it seems that their 91 is like 89.

SO last night I went over all my hoses for leaks. Everything seemed ok, I did notice that my hot side and cold side pipes the clamps were a little loose. So I tighted everything up super tight. Hopefully that is what the leak was. I didn't get a chance to datalog again last night. It was still around 105 degrees at 9pm. I can't wait for the summer to get over and start really enjoying my car again.

The issue can also be the by-pass valve, are you running the stock one? Maybe it's leaking.

I had the Greddy BOV on for a while but have taken off and replaced with stock when I flashed the 1.07 map on. I even put a gasket on with the stock BPV to help prevent any leaking. Also I made sure to check my lines on the BPV and tighten everything back down.
At this point not sure what could be causing such high wastegate duty.
I will get another datalog tonight and see if this helped any.

Build a boost leak tester for a few bucks. Easiest way to confirm.

I've been wanting to build one but I believe you need an air compressor for it and I do not have one. If there are other ways of doing it can you link me in the right direction.
thanks

I'm not sure of any other way to pressurize the system outside of a compressor. Harbor Freight has smaller ones on the cheap though that will do the job. Handy to have to fill your own tires, instead of spending a buck at the gas station. Also at some point you'll be ready for air tools.
