Basically a turbo is a supercharger which is driven by the waste energy generated by ejecting the exhaust gases from the engine, making it a very efficient way of improving performance. Most turbodiesels use exhaust gas recurculation which recycles some exhahst gas into the inlet in cruising conditions in order to reduce emissions. An intercooler cools the compressed air exiting the turbo before it enters the engine, giving a more dense charge of air, and more power than if it came hot straight out of the turbo.
The 2.5 KJ produces maximum usable power between 2 and 3000 RPM so can be a bit slow on the uptake. The 2.8 KJ has a variable geometry turbo, which eliminated turbo lag by behaving like a small turbo at low engine RPM, and by tilting the angle of the vanes inside, reverting to full capacity at higher speeds.

what you think of remapping to reduce pickup,it not a full remap,only on pickup

Dr Mike is bang on ( as usual ), had a test drive the other week and that turbo lag is not noticeable in the 2.8. I drive the 2.5 daily.

Not sure if this re-mapping works, if i was you i'd check vey carefully with someone who has had it done.

You don't want to get rid of the lag and then get 10-15 MPG  :?

was on to the people that do remapping in dublin
giving me a mid remapp which only improve pickup,alittle more toque and extra bhp,its not a full power remapp,can get if l want it ,but l don't
will be getting done next thursday and let you know,what good about remapping,you can change back to first setup

did the remapp/happy  with it /tiny lag/hard to notice it/alot better pickup/gave to friends to try and said new lease of life in jeep,wso debateing if l get k+n filter for it or not/cost me 80 euros at halfords/can get a opel filter that fits kj for 10 euros topared to dealer air filter for 35 euros
it feels like a 3.0 jeep rather than 2.5
