Update:

Re-flashed ECU with new settings (10% boost reduction in 4th gear) and the problem is now fixed, no more loss of traction and car keeps pulling till 170km/h+, however, still losing a bit of traction in 5th when putting 100% throttle and rolling into 3,500-4000RPM range.

Might re-flash tomorrow with 10% boost reduction in 5th gear, probably will have no more problems then... Or.. maybe I can keep it so I fishtail lol.

Also rode on the highway a lot today and the car is super quick, saw a bad driver in a Golf while I was merging onto the highway, he didn't slow down or switch into the other lane to let me in, he was speeding up in the right lane, the one right beside the merging lane.. After merging, I moved over and full throttled past the VW and it felt pretty effortless, was doing about 180 in just a few seconds after merging. If you have the windows down the turbo spool and intake sounds insane, even when stock. The turbo spools at much lower RPMs than stock.
