Hi Rhyso, I'm interested in your comments and would like some clarification. I have to be honest I've never had a car re-mapped or owned a chip box before, and it's something I've promised I'll do this time round with my GTD. I have no idea how they work.
When you say a remap gives sharper throttle response etc, do you mean on top of what the car would be like normally before modification? Or will a chip box go the other way and make it feel worse than the car does as standard.
I'd love more power and the gains quoted here are very attractive. Will plugging in this box give me lower throttle response? Or can I expect it to be the same 'feel' but just with more grunt?
What I don't want is to have added a chip box but I then think "sh!t the throttle feels laggy". "The power isn't smooth". Does that make sense?
I would like the same car but with more power and torque. Would you suggest a remap or a chip box to achieve this?
P.S Thanks in advance! 
Throttle response from the factory is usually pretty dead. A remap greatly improves this and is most noticeable when you are pulling away at junctions etc. A tuning box will achieve the same result but not to quite the same extent
The differences between a remap and a tuning box ares subtle and the difference you'd feel would be largely down to how good the remap / tuning box is. The are many different ways of tuning a vehicle. The hardest part is getting it just right
For example I re-did a BMW which had a very sharp throttle response and had been maxed out for torque but that was leading to masses of black smoke and clutch slip along with the owner finding it difficult to modulate the power
The end result after I had a play was a much more progressive throttle, no smoke and no clutch slip but without reducing the overall power of the car

The devil is in the detail

Ultimately a remap is far better than a tuning box simply because you have more control over the variables
However, not everyone wants their ECU ripped apart so a tuning box offers a good alternative. Just stay away from the cheap Ebay ones as they will do more harm than good
