I'm the guy he sold it to - and it's working a treat. Thanks mate

I got a healthy performance improvement when I fitted the chip (even on the standard exhaust) and fuel consumption is about the same as before.

When I bought the car it had a powerchip that didn't seem to work properly. When I took it out performance improved and so did the fuel economy by about 5MPG. I think it may have been poorly set up or a one off faulty chip, but those cheapo ones on Ebay look well dodgy.

I never had any problem with Superchips...
