Superchips? Crap? Why? - I'll tell ya!
I found out about them 8/9 years ago. Then they were virtually the only people doing aftermarket chips.
Then their power uplifts where in the 15 - 20% range and a lot cheaper £150 to £200.
Now they have gone very conservative and expensive! So now you get 10% extra power at most and its £300 and more! They have gone Chav!
