Count me in as another guy running Full Blown's kit with nasty partial throttle hesitations/stumbles. Been running the kit for about 8 months with various degrees of hesitation/drivability. Idles fine. I've been through 2 different tuners now (Dynosty, Delicious) which obviously points to something being wonky with my setup. Here's a log of the stumble through partial-throttle acceleration:

If what you're saying is true, and it's just the FPR that's causing my headache..... I can't even begin to describe how happy I'll be.
Would something like this be what I might need?

Or do you have another part to recommend?
Thanks,
