I've just got my moho (06 Ducato 120/ Autotrail 630SE, 21k miles) back from Loch Shiel Garage, Acharacle where I live.
She's had her timing belt changed and Quantum remapping from 128 to 160bhp and feels sooo much better even on the 2mile toddle (not toddle any more, Drive!) home!
Broom Broom!
Will fill her up and drive c200miles on Very mixed roads from Acharacle to Fort William, then down to Milngavie(northern Glasgow) and over to Lochore next weekend, so will be happy to provide more info on mpg and performance etc there and afterwards.

That's a lot more power from your engine...might that shorten it's life or are more frequent oil changes or oil upgrades required?

It's a lot more maximum power. Most vehicle engines work hard very rarely, accelerating into traffic gaps or going up long steep hills.
Most of the time they just bumble along.
My car has an eight speed automatic gearbox. The engine speed is a good indication of how hard it is working. It nearly always potters along at between 1400 and 1600rpm. Going up some hills or accelerating briskly, it approaches 2000rpm. But in normal driving that's all it does.
With a manual gearbox, you don't get that same indication of how much effort is being used from the engine speed, but you still know how rarely the engine really is flat out.
When you chip an engine up to give more power, flat out is even more flat out, but it happens more infrequently.

I am not an advocate of remapping ,but have to say most people are happy with the results.

Will be interesting to see your results on MPG. We are thinking of getting our 2014 relay 110 BHP remapped

The clutch should not be affected at all. You should never be using any of the extra power until the clutch is fully connected.
But you're also quite right: more power would allow a bad driver to destroy a clutch even faster.

Clutches do have a maximum torque limit determined by the pressure on the plate before they slip.
Normally if the remap doesn't exceed the most powerful engine option in the range you should be alright.

Just had a look on Celtic tuning and your engine goes to 178bhp from 110 the best bit it gets 100 extra torque.They have done all our vehicles in the last 12years and never had a prob with any of them.

Wow that's a good increase in power I guess from their name they are based in Scotland?

Clutch issues do show after a remap. An old clutch may have a pressure plate that isn't as good as it once was, and coupled with a thinner friction plate it won't be able to support the torque it did from new, if it was even capable in the first place. Motorsport Developments in Blackpool used to run a Ford forum I used a lot and he was constantly saying there is every chance a power hike will highlight a tired clutch. I went with a mate and his 5 year old Golf for a map and it slipped on the way home.

And, of course, some data for you:

Agreed that a power (or more precisely torque) increase will more rapidly show up a failing clutch, but if the clutch wasn't failing, it shouldn't be a problem.
Interesting that you mention Ford forums. In my experience, Ford is generally the brand with the lightest and easiest gearbox and clutch, and also the one with the most fragile clutches.

Yea, some can be a bit crap. Same as any brand really, different models have different quality. The one I was most interested in was the Escort Cosworth. It was initially sold to the public for homologation purposes where it had to have all of the parts that the rally cars did, but would be de-tuned for road use. In rally guise this would be 330bhp with similar torque. Joe public got 224bhp, but a chip, injector, air filter and exhaust swap saw the 330 restored quite reliably. I was on various different rolling roads with the club and saw average 315hp and 315ft/lb. I ran it like this for years as a daily driver, abused regularly without any trouble. After 10 ish years 3rd gear had broken, it's in the middle of the gearbox shafts and they flex under the torque. Coupled with the fact you spend quite a lot of time under heavy load in 3rd it was inevitable. The front diff was also a known weak point, but I haven't had any problem on mine. 400 bhp was the next relatively easy step and then you'd see the front diff be more of a problem, and respected people suggested you had less than 50 full bore launches on the 4x4 gearbox before it was turned into swarf. The older 2wd sierra cosworth boxes were easily capable of over 500hp. The lack of grip vs the 4wd is obviously helping, but with suspension mods and decent tyres people were putting the power down quite well. Until the rear diff gave up lol.

The earlier mk3/4 escorts could also make some decent power, and later (Ford) gearboxes were the ones fitted to cope with it.

Ah, fun and games. I really must get it out of the garage!
