Van Aaken Optimisation etc??

Forum: 

Reading through an old 4X4 magazine the other day I came across an article which showed the increases that can be had from turbo diesel lumps if they are set up correctly. I've owned a Daihatsu fourtrak for just over a year and to say the performance is a little disappointing would be an undestatement. Has anyone out there had this done and what have your findings been?? I've had a read through the LR boards and from what I've seen everyone raves about it, but how will this compare to my Daihatsu being done?? (I don't fancy doing it myself thats why I'd quite like mr Van Aaken to do it)
