Hello all new to the group , I’m in the US I have a imported 2001 focus wagon with a 1.8 TDdi 90HP , I want to get a tune or a remap as you all call it
but I would like a handheld tuner I can purchase and just plug in , I need to know what companies I can trust for this , or can I just buy a remap ecu off of somebody and just install it , I’m wanted a little extra power but also to maintain or increase my mpg , any help is appreciated
