For tuning these vehicle with the larger injectors you really do need to find someone with a rolling road and also the ability to re calculate the injection calibration maps within the software so that the engine control unit is in full control of what's its injecting.

I've seen a number of maps wrote that the tuner simply puts -10% across the full injector duration map, this basically reduces the open time of the injector across the full rpm range which is really defeating the object of fitting larger injectors.

You see these control units have a set of calibration maps that control the injectors that all work together, you have "Start of injection" this speaks for itself and then you have "Injection Duration" again speaks for itself.

So you fit larger injectors that can inject the same amount of fuel in less time than the smaller injectors so you need to adjust the start of injection time to suit this, but also you need to re scale (re calculate) the injection duration or pump voltage maps to suit the larger injectors. (this is a basic example)

Do a little research as there are a number of excellent tuners in the UK.

Hope this helps
