Who has had there diesel cars remapped and were they ok afterwards. Did you notice a big difference in both power/driveability and did you get better mpg.
I'm thinking about getting my mk4 2.2tdci mondeo remapped. I've heard people say with these mondeos that a remap cam wear clutches out a lot quicker??
my merc diesel responded well to a remap, around 270bhp and 600nm from 224 and 510 standard for about £250....its an auto though so don't know about clutches . mpg is not a concern I have either....when it runs out I put more in....
My E91 Bmw 330d was remapped by BWchiptune in London (probably the most well respected and highly rated tuner in the bmw community), and power was raised from a measured 236bhp to 317bhp and torque from a measured 545nm to 673nm. The dpf was left in place but the egr was programmed to stay shut all the time. The map I went for was an 'all round' map as opposed to going for all out power or economy, and the map was written by the tuner himself instead of using a generic map.
Economy hasn't changed - it still returns 50mpg on a decent run and mid 30's around town. Driveability is superb and is just so effortless. Everything is just really smooth, and when you ask for all that torque, theres no fuss, it just pulls no matter how low down the rev range.
Mine is an auto box so I've had no problems and was mapped about 2 years ago I think. Would definitely recommend getting a diesel mapped, but as with anything do your homework and choose your tuner wisely!
My son keeps thinking about getting his 68 plate 2.0 TDI Seat Leon remapped, I assume it's a VW engine so would assume there's plenty of places that could do it
I'm fancying getting my disco 3 done when I pick it up off Martin. Anyone got any experience of these?
I have a 2012 sport which has the 3.0 sdv6 engine in it with 8 speed box which I had remapped by Alive tuning Land Rover specialist and all I can say is WOW.
car drove ok but had a massive hesitation pulling out of junctions and never seemed to know what gear it wanted when putting your foot down.
Remapped and hesitation has gone and now always seems to be in the right gear plus you can feel the torque even on light Throttle. Car now drives amazingly and couldn't recommend Alive tuning enough.
Before 255bhp 610nm After 310bhp 720nm.
Some Landrover’s had plastic inlets that split if you raise the boost
Nothing to do with raised boost pressure but it will find the weak link in the plastic.
It seems to be an issue on older higher mileage cars as the plastic deteriorates with age and the hot/cold cycles and becomes brittle.
This is the problem with moden cars, everything is made from plastic and not made to last like older cars where it's made of metal.
Some good examples there people. Is it better to go to a proper remapping place which has a rolling road. My mate got his xmas 1.6 tdci done by one of these blokes who comes in a van. He said his has been spot on since he has had it done

If you want a bespoke map then go to a proper tuner with a dyno who can analyse the data from your car and then write a map to suite.
If you want the plug and play option go to someone reputable like Superchips and get one of their Bluefin handsets. I definitely wouldn't be going to one of these blokes who turns up in a van and loads God knows what onto your car!
Uses a Transit solid flywheel, car is now over 280kmiles, same clutch and gearbox, only problem has been split oil return from turbo and erg valve, still a fast car even when carrying five people and their luggage.

I've had a few diesels remappped, currently got a grand cmax family banger 2.0 tdci, 140 up to 165bhp. And also my mk3 focus 2.0 tdci, 163bhp up to 185 and 300lbft apparently.
They both go alright to be fair, the focus will leave behind 320d's so that is good enough for me lol.
I had a mk7 fiesta 1.6tdci a couple of years back, that had the biggest difference after being remapped, it was quite a nippy car after. I have never noticed any improvement in mpg though!

I have had every diesel car i owned mapped and the older ones that had no ECU was pump opened up and boost turned up...only had to replace one clutch after a remap been lucky!

It's just a Landrover, everything breaks
I'd be cautious of all generic remaps....even more so if it's a vehicle with expensive emissions gear on it.
bought a Discovery 2 on a bit of a whim at the start of the year, slowest thing in the world, £190 later for a generic remap and wow, the difference is night and day, the clutch lasted 3 days but that's the price you pay.

To be fair, Bluefin isn't very well regarded by many.
A friend of mine has a 1.6 TDI MK7 Golf. Was only 105bhp from the factory. He had it mapped by a "man in van" and said he couldn't be happier with it. They claimed 150bhp from it and I can believe it to be honest. I was really impressed when I've been in it. Drives really well and pulls amazingly hard for a relatively big car with a pretty small engine.
Modern cars are much more advanced and their ability to make minor corrections much better, so generic maps are a lot less risky than they used to be. Think about how many MK7 Fiesta STs and MK2/3 Focus STs are out there with generic maps from the likes of Revo, even with other mods, such as intercoolers/exhausts etc etc. Most are fine. You'd never have got away with that 10-15 years ago.
A custom map is always going to be better, but things have moved on a lot.
Bluefin is what is on both of my cars now and has been used previously. I've chosen it for ease, being able to offload the map if you need to and it is also a code reader. Of course it is never going to be as good as a one off map to suit the car, but I've never had a problem. I would really recommend it.
I had a generic dreamscience map on my focus st back in the day that was uploaded from a handset, that was also fine.
Got my mondeo remapped.
I got told I had to take the ecu out for them to do it. Any way I dropped the ecu off on the 17th July at 3 o'clock. I got a phone call the next day at 8.40am and got told to pick it up.
Its miles better now..2nd gear feels like the car is slightly torque steering. I defo pulls through the gears alot better. I will see if my mpg gets better.
diesels respond well to remaps....what your gains been? im sure its usually inb the region of 20-40% in bhp and torque on turbo diesels so its a noticeable difference !

Yeh its defo noticeable. The map has transformed the way the power comes in.
It is amazing the difference they make, some hardware changes and tweak the map to suit and the gains are even bigger,
My little 123D BMW is now over 300bhp and 600nm on water meth, ran out of fuel delivery on the standard 123D High pressure pump, so had to swap to a 335D pump and modded fuel rail, goes really well and shocks most cars it comes up against on the road.

Remapped diesels
