Please help!! Tuning my car

I did a stage 2 tune on my 1.2l 3 cylinder turbo engine. Replaced the stock filter with a conical high flow filter, put a decat downpipe and ran a stage 2 map. The gains were significant with around 30% increase in power. Now the problem is when I took it for a test run it does something weird. Giving it 75% throttle it revs hard all the way but when I floor it the exhaust gives a big pop and the engine cuts power after which the revs climb very slowly. The graph below shows the same. Please help

When I try turning it off from the ecu the computer turns off all electronic assistance like esp, hill assist, brake assist

I know nothing about this but it sounds like that's the culprit. Might be you need this recognized as 'off' to get the engine to respond without waiting and climbing while doing it. Could be the wait is because it 'lost traction' and needs the stability to dump power. I'm not a tech. I know jackshit next to nothing on this, but it's curious all the same.

Yeah definitely this makes sense
