Whilst not an obvious choice of car to remap, it is still worth doing if only to even out the power band, eradicate flat spots, improve throttle response and just make it feel sharper.
We've tuned my wife's Polo 1.4 16v (AHW) 75bhp (gains circa 7bhp) and it honestly feels like a different car (so much so that she noticed - and she doesn't notice much).
It's all about what's right for each customer. That car won't make easy power like a turbo diesel, but don't write off a remap so easily.
