Any one not got one of these should get one now. 30 minutes to fit. What a tremendous difference. Pulls cleanly and sweetly from 1300 right through rev range. So much more responsive and power there when you need it! Throttle reacts instantly with no hesitation or lag at all. I am also running more economically as can hold a higher gear for longer. I have done over 470 miles on this tank and reckon another 40 - 50 before I need to fill up! I am very impressed.
Thanks Ron.
 
Interesting, I've been humming & hawing about whether or not to get one. What did your insurance company say.
 
Insurance was due for renewal on the 25th August and 3 yr warranty expires on the 25th September so ideal time for me to enquire about insurance and fit device if I wanted it. Present insurer, Tesco, wanted an extra £60 on my premium AND would shove the excess to £500 instead of the present £200. I shopped around and got the the same cover as I have now (i.e. with £200 excess) for the same as Tesco was going to charge me without the modification. This was through Autotrader. They are aware of the modification and are OK with it. So I fitted the Synergy. QED
 
Thanks Dean, I'm getting more & more tempted.
Oh by the way, if you haven't fitted an egr bypass yet do it now, well worth it.
 
EGR by pass? What does that do? The engine is just great as it is now it has the Synergy fitted. What improvement would a by pass do? Sorry to be so thick!

Read up a bit on these and there is a possibility that they can increase fuel consumption and cause it to run unevenly, particularly on tick over. It is just so good right now that I'm not going to tinker any further. Acceleration is tremendous, no smoke and so smooth yet more mpg!
Cheers

I'm a bit surprised about the possible increase in fuel conumption as mine was improved albeit by only 1mpg. Also LRO magazine answered a query from one guy who wrote in asking about benefits & downsides. Their response was no downsides & improved performance and fuel consumption (it was after reading this that I went ahead with mine). Still, if your happy then that's the main thing but keep it in mind for the future if you do get bored & want more. Only costs around £50, is quick & easy to change & if you don't like it, put the old unit back in & sell the bypass on ebay. All the secondhand ones that I've seen still sell for over £40.
 
when you say quick and easy to fit is it on the front right hand side and do you get a gasget with it ???

Yep, that's the one - it has a small vacuum pipe fitted to the front. The bypass didn't come with any gasket & like you this worried me slightly but when you take the egr off you'll find a large rubber O-Ring set in the manifold. My car had done around 53,000 miles & the seal was like new.
 
hi chromiumuk
the valve came today fitted in less than 30mins.What a difference.It seems a good buy.
 
Hi Davie, It was exactly the same result for me, well worth the £50 & the unit is well engineered. A lot of folks on here think it's a waste of money & all you have to do is disconnect the vacuum pipe, but this only gives a very little improvement. As you've found, fitting the bypass is the way to go.
 
the synergy 2 is also great could not beleve what difference it has made to the car.if you have not tried it you should.
 
Davie, you've read my mind. Already have a Mafam fitted & have just received my synergy module this week, so weather permitting I'll fit it this weekend. I'm hoping for a good boost above 3000rpm as low & midrange punch seems good since sorting the maf & egr. My cars an auto & Ron recommends setting 6 as a maximum, so 6 it is & hopefully I'll be pleased with it. Also bought two new intercooler hoses as I've heard they can leak & affect the upper revs before failing completely.
 
set mine at 5 to start with then set it at 10 by god it didnt arft shift but then put my sensable head on and set it to 6 this seems great i have turned the maff setting off for now beacuse when i had it switched on did not seem to make any difference.let us know what you think when you fit it.
 
What is the synergy 2 and what does it do? Does it also apply to the L series engine? And if it is applicable to the L series where do you get one? Cheers in advance.
 
Hi Davie, now got mine fitted & it definitely improves things. Still got the usual narrow diesel powerband, but it has also made some imrovement above 3000rpm. Well pleased. Also replaced my intercooler hoses, old ones were swollen & the clip (the difficult to reach one) on the one at the intercooler was slack.
 
George, The synergy is a plug in tuning module which plugs in between injector rail & ecu and gives a very useful power increase (about 30bhp on TD4 models) over standard.
The synergy is only for the TD4 engine, but Roverron also does a module for the L-series. Pricewise your looking at around £60 & power increases from standard 98bhp to around 120bhp so well worth fitting. Ron also provides comprehensive fitting instructions & is happy to answer any queries.

The link below is to Roverrons website & although it says TD4 at the top of the page, the first section is devoted to the L-series.
