XC90 Turbo chip upgrade 185-210bhp

[n1ckxc90]

This is my C.R. Technology plug and play turbo chip. It's in excellent condition and only been fitted for 5 months. I am now using car for work and have managed to get a remap done for "towing improvements" paid for b the firm.

Great and easy upgrade. Made difference to towing and daily drive. Full instructions given to fitment.

£65ono + P&P

What are these upgrades like on economy?

apologies, been away with work and only just seen this. I noted an increase of around 5-9mpg depending on around town or on a run, increase throttle response is good too.

Common Rail pluggins are quite good.

I've had 2 from http://www.dieselexpress.co.uk for only £90. Performance is adjustable to suit everyones driving style. MPG was the same but I like to use the extra power so didn't expect to see any gains.

I'd agree with Shadeyman and the boxes can be mapped to a number of different driving styles, I wanted mine as an all rounder and so didn't go with the maximum power increase and settled with a combination of a medium increase with the benefits of low end grunt and some good fuel savings.

Under advice from the tuning firm I bought my box from I found adding a high flow air filter (K&N) and using premium fuel made a difference - especially to the MPG and when towing.

I've been looking at buying a high flow filter(this one: http://www.knfilters.co.uk/search/pr...x?prod=33-2972). Did you notice any increase in induction noise ?

Also have to be very careful with re-oiling these filters as the oil can cause problems with the MAF Sensor.

Would you say that a full remap is better than the plug in now that you've had both? Which remap have you had, Polestar?

[n1ckxc90]

TBH they are about the same, on start up you hear the revs change with the tuning box, not with the remap - if I was paying for it, I'd have stayed with the box so that I can change it and have it remapped to another car. I had a local firm do my remap, customised to the car - not polestar - but made for lower down grunt, towing and upto 70mph. It is running 215BHP - ish and the difference is about the same as the box. It cost £220 inc VAT which is £300 cheaper than a polestar. Like all remaps it stays on the car so the cost cannot be recouped.
