I'm having a problem where my car will hit fuel cut or at least feel like its hitting fuel cut as soon as my boost gauge hits 0. I dont know if anyone else has experienced anything like that. I've done a little searching and not seems to quite fit what I'm experiencing. Any ideas??
Fuel Cut at Zero Boost

Well are you giving it lots of throttle like your trying to boost?
Have you checked your codes? Even if the light is not on.

It'll happen at about 20% throttle (according to SAFC) and if I got full throttle it will cut in and out, unless I'm already up to speed and in either 4th or 5th gear. Also no codes.
I've adjusted it before everything seems in spec. Only thing that had me wondering when I was trying to calibrate it felt like it does the opposite of what the instructions say. ie step 12 of this guide http://mkiiisupra.net/bbs/showthread.php?t=12132&highlight=guide+cam I start with zero resistance and deflect to infinite and set it there
A tps will not do that. Sounds like u have a large boost leak

Boost leak usually comes up with code 34. He says he doesnt have codes. Still wouldnt hurt to check for one.
That makes sence. U sir need a smaller turbo!!!! Jk sorry for the derail
Well a tps sure wont do it. I havent had a o2 sensor signal to the ecu for 4 years and have still not gotten a code for it. Does the cel flash on when this happens?

Cel does flash when you hit fuel cut. Does not stay on. Tps can make the car cut in and out below 3k. Kinda studder. Similar but not the same.
Still wouldnt hurt to check for a boost leak tho.

Thanks guys my cars at the body shop now but after I get it back I gotta try the boost leak test. And yea I hasnt given the fuel cut code but it feels like fuel cut
Bad knock sensors or wiring? Should be throwing a code for it, but it kinda feels like fuel cut and it wont make your CEL stay on.
