Welcome to AO
zbrskz (member on here in Portugal) is running 480Nm in a 1.9 JTD with hybrid turbo, try sending him a message.
I get flywheel shudder in my 2.4 JTD if I drop the accelerator at 2,000rpm in 4th or 5th - my solution is to drop a gear, to bring the revs to 2,500-3,000 before I put my foot down. Heavy in first gear gives it a bit too, but its never done any harm in 35,000 miles. At the last clutch change the DMF was in perfect condition, on its original at 122K miles. This is a remapped 2.4, torque around 420Nm or so.

Back on the road: Alfa 156 3.0 24v V6, Silver with red leather, Q2 diff, GTA Teledials, headlights & inlet manifold, AutoDelta carbon intake,
decat pipe and SuperSprint rear box, FK coilovers, Dastek Unichip - my 245bhp beast!
Gone but not forgotten: Alfa 156 2.4 JTD Veloce, Vela Blu, Angel 'mad map' & BMC CDA, Ferodo DS2500s - the fastest tractor in town!
AO 'Bratpacker' No 5.
