has anybody had experience of this, or is it too good to be true?

[markey mark]

feedback looks good for money its a bargain

[mark3]

its got me interested!

[Entwood]

Just wonder what that would do to the AR25 box .....  might last about a week

I'm happy with 217 BHP

Nothing, the 2.5 develops a peek of 227NM of torque and the chip is unlikely to do much to increase this, the AR25 is rated to a minimum of 250NM of torque.

do you really mean "minimum" I suspect its a maximum ...  

From the advert :

The power gains are very appreciable, up to 191HP and 261NM on engine with stock camshafts

I guess just 11 Nm over the top is not a great deal, but I'd be concerned ....

Ive got a Superchip in my MV6 3.0, cant honestly say I notice much difference (supose to be about 15 to 20 BHP more). Maybe slightly better MPG.


I got a Courtney Chip on its way, to see if thats any better.

I think with this sort of thing you really only notice the difference (if any) is when you drive for a while and then put them back to standard!.

Post back your findings if you go ahead

I'd be very surprised if it made anything like that. Peak torque is largely relative to engine capacity. It generally peaks at low revs with standard cams so how well the engine is breathing doesn't really come into it because the air flow rate is relatively low.

You might improve it a little over standard by running a less "safe" ignition map (although on an efficient engine like the V6 it's unlikely to need critical levels of ignition advance to make best torque). You are not going to increase it by 15% that's for sure.

I had a similar thing (superchip) fitted to a Discovery TD5 a few years ago. Mildly improved the throttle response, but did wonders for the fuel economy !

The only problem I had was that the extra MPG was often cancelled by the extra weight that had now been added to my right foot.

Turbocharged engines (petrol or tractor) are a totally different kettle of fish, of course. Much more potential to tune them.

No, I mean the minimum torque that it will continuously tolerate is 250NM but, likely to be higher than that.....

And if that chip makes that sort of gain in torque I would be very surprised!

if this improves the MPG, it's worth the 50 quid alone. I can't really see as has been said, how the torque and bhp can be improved by the claimed figures, but if the fuelling is sorted then that's great.  I'm seeing around 22mpg according to my display at the moment, and while I understand it's a V6, high 20's would be nice.

i bought one of these and it made the engine and tourqe delivery smoother got rid of the flatspots

it made the fuel economy worse lost 3mpg


Had my car dyno'd but im at internet cafe so cant post dyno readouts but can emasil them to ppl if you pm me

but i gained 9 bhp and 15lb/ft of tourqe that was on a 3.0 MV6 though

in my younger days i spent a lot of time tuning the 2.5XE, it is a really responsive engine when the right mods are done and it does respond well to tuning.

However 191 from a chip alone is a very tall order, i would expect to see 10% from a chip, then add the cams and a good airfilter that has a cold air feed and i would be looking at 200bhp.

Throttle bodies, porting, sports exhausts and a few other little tuning tricks would see another 25/30 bhp but then you are into the realms of spending large amounts of money on internal components that will be able to keep up with the rest of the set up

The mpg difference will not be in that sort of order. It will be minimal - 1mpg at best.
