Magic Powers Loss, Full power then GONE! then back again! MAGIC

[Bait_Fish]

Hey guys,

PROBLEM!! for a little bit now my baby gal has been acting pretty weird. when i take her around a corner with a fair bit of power or do a u turn with to much power causing loss of traction, she DIES. it almost feels like traction control, now its only a forte S3 so i guess its not that. Shes Auto with 80ks on the clock

i'll set the scene for yas, parked at front of the house, no cars coming, feel the urge for a rather fast u bolt, foot goes down, baby starts turning, wheels start to spin then about 3/4 way through she stops spinning the revs die but sort of build up again n off she goes down the road on her merry little way like nothing has happen.

it seems as though its getting worse but, nearly every time i take a corner now n carry a few revs she likes to have the power disappear n reappear to make me look a fool .....

What’s could be the problem guys? i'm guessing there could be a few things but where should i start?

i had the gear box looked at recently because when i was taking my foot off the accelerator she would drop back a gear, that stopped n they couldn’t find anything wrong with the gear box... so maybe fuel? leads? spark plugs? ecu? some sort or sensor? i'm at a lost guys any input would be great!

So far it only does it while cornering with power to, not in a straight line, over taking or even taking off with 2 grand of revs….

thanks for your time Bait fish....
