04' WRX swap STi

Default Weird Jerk motion when in boost.... help

My car is as stated on the left under my username, other mods are simply an exhaust and intake. I've been noticing, especially now after my STi 6MT trans swap the WG tends to flutter WOT in gears 3 / 4 / 5. At first I was guessing it did no harm since it did not feel like I was losing power. Nonetheless for a while now, when in WOT after the fluttering has stopped a few seconds later the car will jerk (like if I shifted) and then go balls out fast. All in all, I was wondering if this 'fluttering' is doing harm? and what are some options to remove the fluttering?

--- the turbo is a vf37 (twin scroll turbo)

thanks so much in advance,
