Do you have to code the diesel injectors when replacing recon units on a freelander 1 TD4 2003? If so would it be better to do a remap & larger intercooler at the same time? Cheers

Hi, I own a 2003 freelander 1 TD4 and I'm looking to install a 2" lift kit. I will also need new shock absorbers. I've heard muddymods supply a good kit. Your comments greatly appreciated.
