but yours has nicer wheels

Most people seem to think a remap's better tha the tuning box. AFAIK the box just 'lies' to the ECU, telling it the fuel rail pressure is lower than it really is, so the ECU increases it,,thus giving a bit more oomph....
On the surface of it, you'd think an intercooler would help, but I've read some views to the contrary on here. You can get about 120 bhp with a remap, I think.
