I have the same engine and gone down the re-mapping route.I would highly recommend this upgrade for the 2.8 JTD.
The increase in power is evident,particularly on long uphill gradients where previously I would have to change down to 4th,the truck will now sail up in 5th-and I have the long 5th gear,it's also useful to pull away from the HGV's on the motorway when they are playing sily b*****s
There are some re-mappers on here who have good reports from members,I chose someone off of e-bay who came to the house to do it.Took him all of an hour then a test drive with a guarantee of a full refund and returned to the original settings if I wasn't completely satisfied
I haven't noticed any difference in fuel economy or smoking from the exhaust,in fact I can't see any downsides really,except it may invalidate the engine warranty-if you tell them

I too have the 2.8 JTD engine & have just booked it in to a local tuning specialist for a 'Superchips' upgrade. there is no way i would ever be brave enough to get something off Ebay for my pride & joy, so have gone for perhaps one of the most recognised names in the business & fitted by a long established company - where i can call upon if all goes wrong. Yes, i have probably gone for the dearest option, but i don't want to be stuck somewhere in the future, broken down, thinking why didn't i spend that extra £100. booked in for May 11th so will report back with results. Tuner said i should expect a 10-15% improvement in fuel economy & also said it is an approved upgrade by many manufactures & won't invalidate any warranty. this is a permanent upgrade tho' as it involves fitting a new circuit board in the ECU.
hope this is of some help.
I fitted a chip box unit 2 years ago to our 2.8jtd and it did make a big difference. It took me just 40 mins to connect it all up. If i change the van for another 2.8jtd the chip box can be taken out or sold ..
If superchips are stripping the ecu to fit a new eprom they are using old technology and today this is not neccasary as this ecu can be programmed through the diagnostic port,therefore reducing the risk of bad solder joints and breaking the ecu seal and moisture contamination.We have the latest software and have the uk licence for it,when our modification is in the ecu it can not be detected by the main dealer as the flash conter is reset prior to us working on the ecu.

Excellant job, best £299 I've spent on Hilda. We now travel virtualllly everywhere on main roads in 5th gear and are comfortably able to overtake with easy. No having to change down gears. It will also pull us up quite steep hills now in 3rd or 4th gear whereas we used to struggle in 2nd or even 1st.
Probably not given any benefit on MPG but then that was never an issue.
The comfort of the driving style now makes even Jean happy to do a stint behind the wheel.
Also you'll find that Harold is also a member here and his No quibble guarantee speaks very highly of his product. I doubt that we will ever have to see him again ( in the nicest of ways of course)
Would definitely go for a remap over a tuning box and in any case never buy a tuning box from Ebay. Have got both (not on same vehicle!) The MH has one done by Darrell of Torquing BHP - good solid remap and huge difference to the van. The other is a spider "smart" unit which I can transfer from car to car if I pay a small fee and send it back to be reprogrammed.
If I was keeping a vehicle any length of time a remap from a reputable tuner such as boosters will completely transform your motor
a quick update to my earlier post - for anyone interested. Superchips agent informed me that my chip was not flashable, so fitted a new chip. He had done this many times before & convinced me that this wasnt an issue. Anyway, definately a marked improvement in both performance & fuel economy. Taken the van over to W Wales & W Yorkshire, both involved some decent hills. the van will climb the hills much better now but there is still a bit of working the gearbox needed. This power/torque improvement is of most benefit on the motorways where the van wil now go for much longer without losing speed on those long inclines. However, where i used to just give up on busy motorways & sit behind the wagons, i now overtake them all. yes i get there much quicker, but i'm not half as relaxed at the end as previously. if i drove as before i think there would be a huge improvement in fuel consumption. So i think a change of driving style is needed. Anyway, a recommended upgrade especially for a heavier van & would certainly do it again, just dont expect your van to perform like your turbo diesel car.
