I've just bought a 2007 Kia Sedona for family motor and, more importantly, caravan-hauling duties. Whilst I'm expecting far better performance in this role than the outgoing Citroen Xsara Picasso 1.8l petrol, it would be nice to have the promised extra 50 NM of torque and 4-6mpg. Has anyone had this doen to their diesel and, if so, was it worth it, what was the mpg like afterward and were there any issues with the car i.e. faults onhe engine, accelerated wear on clutches etc?

On a similar theme, my saab turbo has had a lot of ecu tinkering and hardware upgrades.



Its gone form the stock 205bhp to the 290bhp mark now.



Still does 30mpg like it did prior to all the work, has the original head gasket and clutch in 50,000 of my motoring miles.



Pulling vans is heavy on clutches, but I think that will have more impact on the clutch than the extra nm from upgrading your ecu.



And how the Kia clutch quality deals with that hump....

I've had my diesel tweaked.

233bhp stock, now 285bhp. 450Nm before, 560Nm after.

It still achieves about 30 mpg which is what it did before. I could do better, but I get tempted too easily! I've had no negative effects so far. Even had some warranty work done at a main dealer and they didn't bat an eyelid.

I'm running an auto though so no worry about clutches!

were do you get the upgrades done?

Although i am quite happy with the way my Mondeo 2.0 TDCI goes, and MPG figures

I bought a chip from www.dieselpowertuning.co.uk 4 years ago at the autosport show.
£280.00 just plug in and go

its for my ford transit 280, 75bhp. I specifically asked for more torque & power to tow my race car around the country.

it boosted power to around 93 bhp and the difference is amazing. same fuel consumption, a lot more flexible in gears also slaughters the long gradients on the motorways

I had JR Tuning in Kent do it for me. Basically plug in to the laptop, download the existing map, send 'upstairs' to their tuning guys, have a cuppa, then upload the new version into the ECU. Drive in, drive out in under an hour.

If it's plug in and go then I might well have to get one myself
