If that only cost you £6k, even if it’s got mega miles on it, you’ve done quite well!
Next weekend I hoping he’s got the time to fiddle with it as he said it’s easy to get a reliable 140bhp and 300nm of torque out of the 1.6tdi to play with.
Just had mine done the other week. Went from 95bhp (mine was seemingly a little down as most put out bang on 102 from the factory the tuner said) to 140bhp and 297NM of torque up from 250. Thing is, it drives just like you might expect a higher power factory tuned engine to drive, it’s not peaky at all. Basically, VW engines are designed to be able to put out pretty decent outputs if required, but they limit them via software from the factory. Basically, above 3krpm on the factory map, the fuel delivery to the engine becomes very limited, meaning the torque drops off and the power barely climbs at all. With the new tune, fuelling is much better right through to the redline, and though the torque drops slightly above 3krpm it doesn’t drop anywhere near as much as before, which meas the power continues to climb much further.
Anyway… Long as the short of it is it’s now a nice van to drive. It’s not fast, but it’s fast enough. And unless you rev the nuts off it all day every day, it shouldn’t affect the longevity of the engine either.
