A decent air filter and exhaust is a must.
Forget superchip.
For easy stuff you have a choice of stage 1 or 3.
My stage 1 got me 288, with exhaust and air filter, but this is very high for a 1.
A lot that do stage 1 go onto stage 3 anyway, so you could just do that to start with.
A 4x4 intercooler on a 2wd works a lot better than 2wd one.
Be sure of what you buy as 2wd and 4wd VERY different to drive, in the wet 2wd can be lethal, but fun!!
Stage 1 is chip, actuator(-31)
Stage 3 is chip, actuator(-31), and DARK greens, 803's injectors, 3 bar map sensor.
Very easy stuff to fit in a few hours and very good power per pound spent.
Later mods would be larger turbo, RS500 type intercooler etc.
Group a coils make a world of difference as do decent leads plugs.
