In that case my mate has a highly tuned MK3 GTI 2.0 8v...

He has put high lift cams, remap, custom filter and miltek exhuast and de-cat.

You could polish and port the head too... Good for 140-150bhp after all the above.

He still can't keep up with me though! ;)
 
Getting up to 130 will cost a surprisingly large amount of money, so save your pennies until you can afford to buy a more powerful version instead of tuning your existing car
