shaun get a remap not these **** aftermarket boxes that fool ecu into boosting extra power a good remap straight pipe bigger intercooler. Just remember it is not a racer it is a work horse. Remp will sort flat spots and give you what you want econ. power. towing or solo, they will map landy to what you want, but a remap will never make a 1/4 mile car out of a 2.5 tonne workhorse called a land rover.
