Fair to say the performance is back......
Full auto:
Geartronic 2nd gear start:
8,9s! No reason to dis-believe it either. It feels about as fast as our MINI Cooper which is 8,5 0-60.
I do like me Polestar, I do...!
Is the 0-60 time display from that canbus extender you bought? That's just going to encourage hooligan behavior Full auto:

I'd be worried about the automatic gearbox with that 240bhp RICA map I think, I have a MTE 225bhp map on my C70 D5 and I suspect even that 25% increase in power and torque is going to significantly impact on the lifespan of many components. Even more power and torque through an autobox already at it's limits plus the weight of the XC90 is surely not a recipe for longevity and trouble free service

Managed to catch it in the act whilst recording the boost pressure. Areas highlighted in RED correspond to me feeling the reduction in power in the car and the orange triangle of doom appearing.
During all runs, throttle pressure was constant at around 50%, and there were no gear changes. i.e. all are in-gear accelerations.
First occurrence looked like this, with a flat line:
All subsequent ones look like this, with a more pronounced dipping curve - I experienced this about 5 times in total, but only screen grabbed two of them.
Every time they set the 2xECM DTCs for MAF and Ho2S.
(peak boost recorded as 2700hPa, which is about 39psi).
I responded to your post on the Volvo forums, however my MTE remapped C70 D5 hits almost exactly the same peak boost as yours. 25PSI would be very high boost for a petrol but from what I understand this is not unusually high for a modern diesel engine. Still need someone to find out what a stock ones does. I also graphed the requested boost level from the ECU against the actual MAP and they track very well, so it's not overboosting.During all runs, throttle pressure was constant at around 50%, and there were no gear changes. i.e. all are in-gear accelerations.

Cheers! I think I replied over on the Volvo forums (but maybe not!) 
The response from Polestar was utter garbage, no help at all.
Seems like 25psi might be OK then - my turbo is certainly very 'vocal', but its always been that way and hasnt changed over the 40k miles ive done in the car.
If I ever end up buying another (std) D5, its going straight to RICA. My Uncle in Law has a 240bhp map on his 185 D5 and its like a rocket ship in comparison to the standard car.
I'm extremely pleased with the MTE map and I've had no problems in about 30K (aside from needing a new clutch straight away The response from Polestar was utter garbage, no help at all.

). My turbo is also very vocal, lots of whooshes and other most un-diesely noises from it. I wouldn't hesitate to recommend the MTE map, and I don't think I would be very happy at all to go back to the standard map now.JakeT said:
The D5 seems to be a very vocal motor generally. Makes lots of nice turbo noises for a diesel! Better than the boring VAG units that just clatter about...
Mine is a diesel convertible, and I will openly admit that I enjoy the engine note from the thing with the roof up or down. A real dirty offbeat growl with lots of whooshing and whistling from the turbo to help things along. I found the engine noise from my V70 T5 a bit odd, from inside it sounds like a sewing machine but from outside (usually as my OH boots it down the road) it sounds superb.kapiteinlangzaam said:

If it's not rude to ask.
No probs at all.Rough calc is about 25-30p per mile, excl. fuel and insurance.
With those included, somewhere around 50p per mile.
Costs would take a jump again around April, as it would be due another 800eur worth of tyres.
My previous gen. V70 was about 15p per mile (or maybe even less) from memory!
