I have a Kia Sorento 2013 2.2 turbo diesel. I was reasonably happy with the overall running but with one fault. If driving slowly in traffic or at an intersection there was sometimes extreme lag when starting off or trying to accelerate away, even at a reasonable pace. I tried injector cleaners etc. but nothing changed. Since installing Hikeit the problem has gone! I am set on Cruise mode1, and its very smooth and hard to even notice the auto change, but there is plenty of acceleration if needed. When I go on my next trip I will try Eco mode, I'm sure it will be a winner too! I love the range of settings and I'm sure everyone can find one they love.
