I'm exactly the same with mine bud!

You could go for a UT T38 and a chip or live map to suit....You'd run over 400 easily on that

You'll be looking at around £600 for the turbo second hand (think theres one in the for sale section on here) and I think a live map is around £500 sheets

Or have your's set up to spike at 2.2bar and hold 2 bar same as mine

Honestly though bud, I would leave it....thought about upping the power on mine aswell but all thats going to happen is the gearbox and diff will suffer!

Converting to RWD is a good idea...it'll feel much more angry on boost as there wont be as much grip lol

I've got a pair of front koni's you can have for nowt if you decide to go down this route
