Re: where to get the uni-chip?
The Unichip (and others) will just make the most out of what your car can do. That is, they add power but only up to what your car is currently capable of. So, if you do more mods you'll get better results and be able to tune your car according to what mods you have.
Mine for example did 134kw with exhaust only. With the chip it bumped up to 146kw. Your factory computer can't properly make use of the changes you make to your car so the chip lets you re-tune it so it does.
I'd be looking at least exahust(inc extractors), maybe a better air intake. If you do internal mods eg cam, even better.
However even on a standard car you will see a difference.
