Hey everyone
I have just joined this forum
I purchased a 2018 mustang GT Performance pack UK model low miles
Good condition 10speed car
I think there is something wrong with this car
I have 04 GT supercharged 05 GT and GT500 2009 5.4L bone stock
Since 2009 i purchased this S550 platform facelift mustang
And my knowledge for mustang is limited to sn95 to s197
So the issue is when I accelerate the car it slows down as it crosses 5k rpm and goes slow all the way up till 7k rpm
Its perfect daily...
