Been tinkering with the idea of a map for quite some time now, but saw a decent kit today and not sure wether to go all out taking it to Darkside Developments for more power (and money). The car's a 1.9tdi 5 speed 130bhp, gets 170bhp with a basic map but the kit gets it to 220bhp. Only thing is I'm not sure wether the kit will be a slippery slope to bankruptcy as it will surely need a better intercooler, clutch, flywheel, maybe more (... either way it'll probably need the clutch and flywheel). Also seems everyone goes 6 speed although I can't understand the benefits of 6 gears and have no idea how to go about sorting that if needs be.
Here's a link to the kit: Darkside 1.9 & 2.0 TDI Budget Turbo Kit inc Fitting and Mapping - Darkside Developments
