Whilst i dont (hardly ever) agree with Ekona its all about the drive with these cars Nub, Bhp is just wasted bragging rights as in reality the extra 5-10 maybe even 20bhp you hope to gain will be irrelevant. He is only suggesting that maybe you may enjoy the car more (as the Op does) if you feel you can exploit its capabilities, rather than just straight line squirts. It doesnt mean you have to go racing around on the roads, just that you may feel more confident to use the chassis in a more dynamic way and perhaps once you get to feel that confidence, you may decide that to go faster or use that hp you have, a decent suspension set up will be make your quest for a very very mild increase in bhp seem totally redundant. Trust me, if you feel you can put that power down off a roundabout as you say you enjoy, 10 or 20 yards earlier, you will be off down the road quicker than the guy with 10 or 20bhp more.
Food for thought imho
