Good evening all.

Now before you jump with "use the search, it's been discussed before", let me assure you it hasn't, not in depth anyways.
As the title says, looking for feedback from people who have remapped a T2 B4204T38.

I have found a tuner who like many others has quoted me 190bhp and 340Nm (picture attached) for £400.

I'm a bit concerned about how this could affect the mechanical parts of the car and if it will cause premature wear. I am aware from reading on this forum that the flywheel gearbox or even the turbo can be affected if you are heavy-footed. I want to hear from people who have done this remap and specifically how it affected their cars longevity.
Also, how much of an impact did this have on your insurance?

Cheers

Hi there,
Assume that the T38 has the same M76 gearbox as my T37 engine? I've been unable to find the gearbox or clutch ratings so not sure of its design limits. Will keep the forum posted if I get any issues as pushing 420nm with my map. Note that the T2 engine is mechanically the same as the T3 so experiences with this engine also apply. The only high torque V40 VEA with a manual box is the D4 and this uses the M66 box - probably for its torque specs!

More digging and the D4's use the M66 and others the M76. However both boxes use the same clutch. From what I can see the D4, T2 and T3 use the same clutch so that must be ok for 400nm. So the most likely items in question are the DMF and M76 gearbox. However looks like the B4304T19 engine which as a T4 can also use the M76 box and DMF as per T2/T3 so should be good for at least 320nm and 290hp. That's the technical info only time will tell the reality!

Many thanks for your efforts, quite impressive discovery, as it can get frustrating to untangle Internet information.
Adding to your conclusion, one must also account for owner's style of driving and servicing routine. Even the type of fuel used.
Hopefully I can get a hold of my insurer to find out how big of an impact the remap could have on my premium and I'll go ahead if not overly expensive.

Insurer denied my modification and on top of that, I have to spend the money elsewhere, so no Christmas treat for me. I hate it when they won't tell you why the computer said'no'.

When I bought my T3 R Design new 5 years ago I was informed by the sales guy that Polestar did an engine remap for around £600 and it didn't affect the warranty, so I was seriously thinking of having it done straight away when the car was delivered from Volvo, but decided to run the car for a few months to get a proper feel for its power, I quickly realised that although the car was a 2.0ltr it lacked a bit of power, I find this engine is a bit revvy but doesn't have the punch to with it, so after around 2 months I returned to the dealership with the intention of getting the Polestar remap, however after trying to book it in I found out that Polestar were only planning to do a remap for the T3 engine but decided to drop the idea !
Gutted.

For obvious reasons I didnt want to go outside of Volvo whilst the car was still under warranty , but since the warranty expired I've toyed with the idea many times, however as I've now had the car 5 years, and I get itchy feet with my cars after around 4 years I'm looking to pass it on in the new year, so won't bother now.

I did enquire with my insurance company about any increases and was told there would be none, but as said that was around 5 years ago, I'm still with the same company so I would guess that if I did get it done there wouldn't be an increase, but knowing insurance companies you never can tell !

It depends on the insurer. I am with Hastings and they were very firm they'd void my insurance if I remap. Also, it would be more expensive to cancel with them and switch to a different insurer.

Yeah each insurer has a different set of rules, I'm with Quote Me Happy, have been for years.
It's usually though the underwriter or parent company that sets the rules.

Sometimes if you read the small print you'll find that many companies are actually the same but using different "shop front" titles.
Quote Me Happy are in fact Aviva, but I bet if I went direct to Aviva they would be more expensive and have a different set of rules.

Direct Line, Admiral & Privilege, are all owned by the same parent company yet I bet each one will have a slightly different set of rules on their policies.
It's a way of being able to offer different types cover through different "shops", one might refuse you for a modification but their partner might accept it without penalties, and.

I might be wrong but I think Hastings Direct are a single insurer, no "sibling" partner owned by the parent company Hastings Group, so there's little chance of leeway in their rules.

Here's an example of shopping around.
My dad has been with Esure for countless years, his premium has increased yearly, 2 weeks ago he had his renewal notice it jumped up by £128, compared to last years premium, no accidents in the last year or driving convictions, he was simply a year older, so I looked around for a different company, I found a decent quote off Admiral, but when I declared a minor bump that he had 4 years ago, the quote went from £550 per year to £765, so I then tried Direct Line and with the minor bump declared he had a quote of £448, plus it offered more cover.
Yet both Admiral & Direct Line are owned Natwest.

Ok it might just be a sales ploy to get a new customer but even if it jumps up next year I'll look elsewhere again.

I always shop around when it comes to car insurance, not just for the best price but types of cover as well.
