s300 and SManager software questions & answers

Hey everyone! I'm having a weird problem with what I believe is my TPS. I just picked up s300 v2 for my fresh vitara build. I calibrated the TPS with no issues and under sensors it reads just fine when the car is off with datalogging on. However when I drive the car I seem to get a 0% reading on the TPS and whenever I hit ~2000rpm the car just completely cuts out and doesn't respond to throttle until the rpm falls back down to ~1000rpm. Is this just simply my TPS that needs to be replaced? Just weird how it appears to work with the car off but doesn't like to work while driving the car. I attached a datalog to show what's happening.

so I replaced the tps, still doing it. What I figured out is the tps is actually reading but there seems to be a dead spot for the first little bit of my pedal. After that dead spot is when the tps begins to read, as long as the tps is above 0% the car won't cut out but as soon as I let off the gas it cuts. Is there something in the ecu that may be causing the car to cut out while I'm accelerating with a tps reading of 0%? How do I go about making the tps read as soon as my pedal pushes in? Would tightening the throttle cable do so? It didn't cut out on the stock ecu and had 0 problems so I'm not sure what's going on.
