2018 TRD Between 50 and 80 Kilometers ???

I bought a new Tac last Spring ,a 2018.
From the first week,when i got it,it does run nice,
BUT,from 50 to 80 kilomters,i always thought that it was not slow,but very slow.
Seems like it does nt response,and almost feels sometimes that it is buckin at times..
I kept telling my dealer this story,until yesterday I asked to try another Tacoma on the lot.
It had 12,000 kilomteres ,but a 2018 ,same motor,but basic model.
So i went for a spin...Did nt take me long to realise that definitely something has to be wromg with mind.That Tacoma ,,sure does responds way better then mind from 50 to 80 ,,it is not like my 4 liter i had before in my 2007 but Man it sure moves,,,my Tacoma feels like it s sleeping from 50 and up to 80 about.So i went back after a short ride of that Tacoma,and told them to give me an apointment.Friday ,they should look into it.
Let s just says ,i am not happy with it,,even less happier now that i realy know that someting is nt right! I should have went back at the very beginning 6 months ago....
Any cleu,or suspicions of those who knows what i may have?
I hope that they fixe this,,,they better!!!
Really too bad because i like my Tacoma,but this performance issue is making me think of even selling my Tac..if they don t resolve it..
