0-60 isnt everything mate...

Not everyone can hit the facvtory 0-60 times either...

Mid-range is the real world scenario and you should wipe the floor with him...
 
Is assume it is the massive amout of torque that causes my car to wheelspin. Is there anyway round this. Can I get my car remapped so the BHP increases and the torque either stays the same or decreases a little (or would this be pointless, if possible)?
Yes you could get a custom map that reduces the huge torque surge at lower revs, but maintains normal torque (& hence bhp) levels higher up the rev range.

If you think about sprinting from standstill, generally you start off in first gear and accelerate throughout the rev range, right through the big torque peak which causes the break in traction.
Once on the move and accelerating hard through subsequent gears, you will most likely never drop below 3-3.5k rpm.

So if you had a custom map with torque reduced at lower revs, you'd be less likely to break traction, and still keep maximum power at the higher revs when going through the gears.

I've had a mild version of this done to cure my clutch slip.

How far you'd have to reduce torque to limit wheelspin would be an interesting experiment.

But first I'd check the following (in this order):
1) Wheel alignment
2) Damping
3) Tyres
