now then folks, i run a modified 325tds. my mods are, de cat straight thro exhaust with a pajero back box (short and same size bore), chipped, k+n panel filter, uprated front mounted intercooler (good for 300 horses), manualy turned up boost, adjustable boost valve. to give you an idea of the torque i can sit on the arse of my mates e36 m3 from 60 to110mph in 5th gear no problem!! the front mount and the chip got the most out of the engine really, but all the mods together are the nuts!! comon rail diesals like yours have a lot of tuning potential but its all about the torque not the revs!
