Shaking under boost

[Noefearsupra]

Alright so I've been looking around and searching for this problem and the only solution I can find is that there is a boost leak but I cannot find any! When I am in boost, the car starts to vibrate kinda bad, not horrible but its definately noticable. Also I believe I am hitting fuel cut because at WOT it doesn't like to go past like 5200-5300rpms. Any ideas on what is causing this would be great, or any more ideas on where the boost leak could be would be great.
Thanks guys!

Boost leak you'd have to find on your own. Search up how to make a DIY boost leak tester and it's a very simple process and shouldn't take much time at all as long as you have access to a compressor.

Are there any codes?

I've got a code 51, which I believe is my tps and I already have a spare one I picked up just haven't installed it yet.

Install it and adjust it correctly then adjust your timing accordingly and see if it still shakes.

Checked my codes again ealier after a little drive (blew a damn coolant hose, think my thermostat is shot!) but I have 3 now. Code 51, 41, and 42. I am not exactly sure where the speed sensor is for the code 42. Also, correct me if I am wrong but are the code 41 and 51 caused by the same thing, the tps?

Alright so I've noticed that during 4500-5200 rpms the car vibrates and after that at WOT it xlears up and runs smooth. I am also only making about 5psime on my aftermarket boost gauge.
Thanks guys!
