I've read alot on this topic on various sites. The majority of people favour remaps due to a tuning box being a preset electronic box that does not take into account the characteristics of each individual vehicle. Can someone tell me if all remaps are unique tailored for each vehicle or whether they too contain predetermined settings ? Or are there different types of remap ? I have a 2.0TDi 140 that isnt as responsive / rapid as I would like, and would appreciate any advice.
