In the time honoured fashion of reviving old threads and due to the fact Im probably gonna be spending to much money fixing up my van so Im thinking may as well be hung for a sheep as a lamb.........................Who do folks recommend in the south west of Englandshire for remapping my 05 175?

had a map from celtic in roche on my 130 about 3 years ago very impressed with the whole thing torque power and improved mpg . they did it properly on the rolling road before and after and gave me a proper printout from the dyno .
my bigest fear is that when I die the missus will sell my toys for what I said I paid for them

I have personally undertaken about 150 Remap's on my own and customers cars and apart from the crazy minority most Remap's are for better drivability and increased mpg my T5 173 is running 210 bhp although I rarely use it, the fact is I don't have to rev it so hard or change down the box so often, and 50mpg when driven carefully is a great bonus, on a long run even at motorway speeds I will achieve 45+ mpg
I don't think it matters about weather it is remapped or not, if you are breaking clutches and drive shafts you are probably driving it too hard

I agree the t5 is to easy to abuse . But 45 mpg ? What engine is getting that mpg . My 2.5 is roughly getting 32mpg whatever I do with it . Remapped to 200

45mpg from a 1.9 maybe but not a 5 pot...32mpg I get from mine which was running 287/580nm until..I cracked the head and lost an intermediate gear on the engine geartrain for the camshaft.
Agree with more loading on the drive train but it's how it's driven, yes most maps on the 5 pot max the torque at 2300-2700rpm which is just above the sweet spot of 2000rpm @70mph in top.
My gearbox gave up last year at 220k and had the first motion shaft bearing problem which is common on these gearboxs anyway but I also wore of the case hardening on the gearing especially sixth...possibly due to torque rather than bad driving. It could be the fact that in any gear my van would pull far quicker than in standard form and I've onlyhad to replace one drive shaft, they appear to go on non mapped vehicles as well.

Mine is unmapped and on a flatish run if you really pay attention to using the lightest throttle possible you can get good figures on a five pot.  On a crack of dawn run from Newquay to Weymouth I once had mine showing 44 MPG on the dash.  I was deliberately driving as frugally as I could to see what it could do.  I have checked this against tank to tank and the dash display is always about 10% optimistic so it must have been around 40mpg.  

If I drive mine without thinking it's around 30-32 mpg and if I'm really in a real hurry around town loaded up with tools it can get as low as 27mpg.

If I'm towing (about a ton) against a headwind on hilly terrain (like Bodmin Moor) it can get down as low as 22mpg.

My missus drove it for a few miles for the first time the other day in South London and she had it showing 37mpg!
