Hi all,
I have a 2013 F20 116i auto and was looking around to see if there are some tuning to increase torque and HP.
I came across few brands such as Hartge , AC Schintzer and another one , they all seem to be adding some torque and power at very high revs and speed and not much at lower end ( 1500-3500 RPM and between 40-100KM) . I wonder if anyone has any experience with these products and has any recommendations?
I havent seen anywhere in NZ having those kits , but it seems easy enough to purchase and install . But are they worth $3k ???
Thanks
