Well yes a remap is always preferable and I have had both over the years. The latest 3 channel boxes are pretty good though and the dtuk box I had on my 340i really made it fly, there was a dyno day at Surrey RR and those with various boxes did get some very impressive figures.
Also let's not forget this is from the company who is selling the remap in a box. ( who I will be contacting as well!)
