Doesnt that have that dreadful bosch cp4.1 fuel pump on it? Wouldnt want to try and make it work any harder.
Yea I mean the difference on mine was so tiny it might even be a placebo, maybe.... between 4-6k rpm there is more power.
When I got it done they said "well youd know if it had already been done as it would have the little badge thing on the back"
But I never put that badge on so......
Diesels have always suffered with lack of revs though, so you get a lump of power and then you need to change gear
I've had my last 4 cars remapped and didn't have any issues with them related to the remap. My first two were a Focus 1.8TDCi and an Leon FR170 both with Superchips Bluefin plug in remaps putting them to about 130BHP for the Focus and just over 200 for the Leon on a dyno. I did notice I was getting more DPF regens on the Leon after getting it done. The next two were DS3s, a THP155 and 165, both done by SPTuning to just under 200BHP. My new DS3 is a THP210 and feels quick enough at the moment so haven't felt the urge to remap it. Maybe in a year I'll get the itch and take it down to SPT!
I kind of thought mine was remapped when I bought it as I’d test driven a near identical model a couple of days earlier and this one pulled very much stronger through the gears than the first car, my mechanic is pretty confident it’s an ex police car as it’s apparently got bigger brakes and different suspension to what it should have along with wiring behind the front grill that’s no longer connected - although a D5 Volvo wouldn’t have been a traffic car (they used the T5 petrol for that) maybe it was previously an undercover vehicle or something?
Me!
- As I say above, when I bought my V70 I was very sure it was remapped by the way it performed, didn’t put me off at all, I viewed it as saving me getting it done.

This quote is mostly nonesense tbh. Also, after 50-80k the issues happen? I mean, that is quite a margin of error and not out of the realms of when issues occur regardless of mapping.

Got my polo 1.2 TDI remapped and it is noticeably more responsive and overall drives better.
I was in a forced position however as I needed to delete the DPF and EGR as both were faulty, and a remap, a large drill & gutting of the dpf and an EGR blanking plate later and it's running perfectly. Depends on your needs though I guess. I probably wouldn't for your needs.

Few years back work had a couple of vans remapped for "economy" it also improved the performance, when they were moved on one had 320k miles and the other 288k miles, with no issues we just kept them serviced.
One was a VW transporter 1.9 90hp PDtdi think the remap took it to 120hp, it made the van much more useable and responsive, just pulling out of junctions and keeping up with traffic didn't feel like a chore.
The other van was a 1.6hdi Berlingo, 75hp it was severely restricted by the ECU felt like it had no turbo, and was verging unsafe to drive, the remap took it to 90hp but the responsiveness was vastly improved throughout the rpm range made it so much nicer.
Both occasions the cost was justified.
Fuel was saved because you weren't having to ring the neck out of them to get them moving.
I wouldn't listen to the naysayers who say manufacturers spend millions of pounds on development bla bla bla... Yes they do, but they also purposely put in restrictions to make you spend more money.
A lot of remaps are just taking the restrictions out. Take the 2 examples above, the engines on the hdi were available in 75hp, 90hp & 110hp, the 75 & 90 had the same turbos, the 110 was seperately by a slightly larger turbo, everything else was the same.
The VW tdi engine was a similar story.
I strongly advise to avoid "tuning boxes" these are just snake oil and trick the ECU into thinking it has different sensor readings.so more fuel is added.
Also be wary of "dodgy" tuning companies, the likes of black code are to be avoided at all costs.
My most recommended would be Celtic tuning, but then there are vehicle brand specific ones that I would rate over and above anything else, for VW group diesel cars dark side developments would be the ones to go for.
Avoid avoid avoid generic companies like quantum remaps, black code etc, they are just other maps copied badly, they pretend they have mapping experts, they don't there just a generic map company with little knowledge when problems occur.

Didn’t fancy a new DPF and EGR?…
I don’t enjoy being behind people who clearly have a DPF Delete, EGR etc - Literally can taste the fumes, I’ll always hang back or overtake when possible.
Oh and those burning stupid amounts of oil, you know full well they are aware but just continue to ensure the driver behind can’t breathe.
Not pleasant
Polestar is Volvo's own in house tuning arm, if it were to put excessive amounts of negative strain on the drivetrain they wouldn't offer it.
Clutches do wear though so worst case scenario it will highlight an already worn clutch
What mileage is on the clutch?
It's a myth about police cars being mapped.
I'd rather wager that the map put on your d5 is a poor map put on the car, or it could just be the pure dog delete map which doesn't provide any performance gain.
Who was the mapper, was it just some bloke in a van with a kess V2?
