On some applications it will also increase the boost pressure by opening
the
waste gate at a different time.

You beat me to it Andy! Don't forget also that the ECU measures several
parameters, eg exhaust gas oxygen levels, temperatures etc, so it's a bit
more complex than just timing the injection. Waste gates are commonly used
to dump boost pressure to save the transmission. Turbos massively increase
mid-range torque which will often knock out gearboxes if uncontrolled. But
again manufacturers are extremely conservative with this. However it's more
low-speed torque that I want and a turbo won't help that much. A 6-speed box
is perhaps the answer!

Has anybody had any experience of chipping their Fiat Ducato motorhome.

I bought a motrhome that had a 1997cc diesel engine ,Didn't think to ask the engine size when buying thought it woukd come wth the correct engine size.. it's not powerful enough so I had it re chipped and it's erformance as increased dramatically. had it for 5 years now with ni trouble at all. Make sure they fit a larger cooler when rechipping

Ha! You gotta laugh at the previous reply. Steve the 2 litre JTD Ducato engine is turboed and should move just about any van at a good clip, unless something is wrong either with the turbo or the fuel supply. It really doesnt need chipping!
