We have just got back from a trip to the Sth of France.We have only had the van for a few weeks but were surprised how much we had to change gear up hill on our way back in the mid pyrenees.It's one of the reasons we changed to the 2700 cc merc for more power.Should we need to remap or is something wrong with it?
Thanx in advance for any advice.
Don't know how heavy your van is, but ours is 3,800 kg with full automatic transmission. Goes very well and I never use full power. I think you may need to have yours checked. Acceleration is brisk considering the size of the vehicle and it only changes down on steep hills.
Unless you have a very large (5 tonne van, or heavier) you should not need to consider remapping.
p.s. just thought that if you have changed from a Fiat JTD engine you may not be used to the fact that the Merc engine tends to rev fairly highly. It is happiest between 2,000 and 3,000 rpm. Ours sits at around 2,500 rpm when we are cruising at about 55 mph.
On the body and under the bonnet it says its a 3500 but all brouchers say the CI Cipro 55G should be 3800 so im unsure what it is at the moment.
And it pulled well on way down to the Sth of france thru Reims Troyes and to Sanery Sur Mer,and also when thru the Pyrenees was ok.It was just on the very steep climbs it struggled.
I think any motorhome or van will struggle on STEEP climbs, also remember that at altitude the air is thinner so the turbo will work less efficiently. Turbos work best with cold dense air, not so good with warm thin air ie high up in the mountains on a hot day.

Been touring in the French Alps a couple of times with ours with no problems at all. You don't say how much you loaded the van - are you sure you're within its load capacity? Have you had it weighed when packed for touring?
Agree with most of the comments so far. We have a La Strada Nova and our fighting weight is just under 3.3t ready to roll.
Bearing in mind the van is now 9yrs old it still pulls well and believe it or not I have had over the ton indicated.
This was just to prove a point as the salesman claimed it was a 100mph van and not repeated since. We usually travel at speed limits plus a bit.
316 max torque is between 1400rpm and 2000rpm. Mines in a Rapido 9 series with manual 5 speed box & recently weighed at 3400kg. Pulls like a horse and will go right down to 1200rpm before decides to die. Driving it steady but briskly and with plenty use of cruise control and she is giving me just over 24mpg. Remember also if yours is new give it at least 100000 miles to settle in. Sometimes the duller the new engine the better it is as it wears in.

Had no problem in the alps on the way down,only had problems in the Pyrenees.
And i was well under weight with only a couple of bicycles and my Honda gennie in the garage,and didnt use either lol.
As i say is fine in England,so will see how it goes in easter next year when back in France before i do any thing drastic.
Thanx for all your replys guys.
