Hi, I thought the same, so I enquired about a TDI Tuning Box. For same 1.4t First Edition.Is it possible to pepup the acceleration response of CEED 1.4 as I find the car not as responsive as my last car, 1.4 tce Renault Megane?
The Tuning Boxes are quickly and easily removable. Putting the ecu back to its original state.I'm sure you'll appreciate that tuning boxes might have consequences for your KIA warranty. Also, bear in mind that this forum has a presence by KIA Customer Services.
You might find it pick-ups better on 97 or 99 RON fuel.
