What do you think safe max is on long grades?
I got my ecu remapped by a diesel shop here (united fuel injection) a little while back. Huge difference in torque, wouldn't fit on their dyno but my rough calc from before/after acceleration says it should be up around 600-650nm. And it comes on instantly too.
I'm still on the stock td04, and definitely on the limit of it flow wise I think. Fellas down there reckoned other than the tiny turbo it wasn't being worked hard at all, and that if I did a turbo it'd have heaps more potential...
