Hitting fuel cut before any actual cut limits
So Im running a Haltech RE with their harness. Currently Boost Cut is at 14.6psi and occasionally, usually in 3rd gear, I hit a cut well before either the RPM or Boost (havent seen anything over 13.8 on plx gauge or haltech) threshold. Nothing funky in the datalogs and we cant seem to find any other cut parameters that may be causing issues. I hope to get the last log from when it cut tonight when I get home but hoping there is something we are just overlooking and is a quick fix. I've noticed it most in a 3rd gear only pull while doing some road tuning, usually between 5500-6500rpm, if I come to a stop and run 1st through 3rd it will happen but not nearly as often.
Car is an 88 10AE, mild street port, Walbro 255, ID 725 primary 1000 secondary, BNR Stage 3 turbo, Racing Beat RevII exhaust, and an ebay front mount. This also happened on the stock top mount as well.

I am by no means an expert, but are you sure is a fuel cut problem?
When I had the E6K installed (which I purchased used), Brian and Dave from Speed one found out that there was something wrong on the E6K with the signal to the coils.
The problem would present itself similar to what you are describing. I could boost the car, if slowly ramping up on the accelerator; however, if I stomped on the accelerator, the car felt like if it hit a freaking wall.
Fast forward to the PS1000. While upping the boost, the fuel cells where not tune for that particular boost, and the car was SUPER rich. The problem presented itself as if the car stopped boosting, but nothing like hitting a wall.
