I derailed my own thread, so let me get this back up. While researching HPFP's I came across this review by someone who had some issues with his and this upgraded HPFP solved the issues he had. As you can see there's "partial throttle boost" which sounds like the issue I HAD.

I found this upgraded HPFP from a site I've been dealing with for 2 years and pulled the trigger on it. It's a Hyundai/MOBIS part, made in S. Korea in the original box and some hologram mark that signals O.E. part.

Even though my stock HPFP works fine with the stock ECU, worked at WOT with the tuned Stage 1 ECU, I'm hoping it solves the partial throttle issue....thoughts From "stay tuned" to T U N E D !!
