Hello only 2nd time on the forum but here goes. Baught a new Mk3 1.9 TDI SE, what engine mods are possible to gain some extra horses? Been looking on the net and it seems like the best road to go down is a new chip, inductionkit/k&n filter and a uprated exhaust. But what the hell is a tunit? It looks like a small plug that goes in the electrics somewhere, claims an extra 35bhp instantly! But for ?375 seems like a rip off. Has anyone out there had any success with the 1.9 tdi? Any help would be fantastic as I haven't a clue when it comes to diesels. cheers.
