Right Interesting News

Just had a couple of emails from Mike Cooper of DMS tuning, one maill with a number of an Ex owner who had both his Gransport and his Granturismo done by DMS said his GS was pushing around 430 bhp on the dyno after the remap and his Turismo was pushing 470 bhp on the rolling road after that was done , said the best bit was the improved midrange torque and the smoothness of the throttle engagement, couldn't rate them highly enough, said it was well worth the money , food for thought but needs investigating further , Guys name is Barry Coupe , anyone heard of him, he's in a company car now and both Massers are not in his ownership shame eh , ive got his email and will probably invite him on hear to answer a few question

Good bit of research there Loz.......with lots of potential for the forum to explore, would be good to hear a few more testimonials though, and getting Barry on the forum would be useful, good stuff!

Sceptical bugger that i am Frank i'll need two or three at least , and or possibly a go in one that has had it done , now that the kind of proof i would like to arrange something on here as a group buy /open day

Oh eyah he said it takes around 2 hours so possible to get 5 done in a day maybe

Loz,

I would certainly be interested to hear more about the testimonials and if they appear credible to you (including longer term consequences) then may well be interested at ~£700. I understand the new 4.7 litre engines only have an extra 40HPs but was curious why Maserati went down the extra cc route rather than the tuning route if that is also possible. Wondering if the problem with the tuning route is it might have yielded far worse fuel consumption figures?

Many thanks

Shak,

As I understand it Maserati improved the performance of the Quattroporte GT-S by increasing the cylinder capacity, remapping the engine and fitting a sports exhaust system. They also reprogrammed the transmission to allow for faster shifts, stiffened the road springs and lowered the ride height to cope with the extra power delivery. This is a quiite a revision for what amounts to less than a ten per cent increase in BHP.

Regards,

Paul

Hi Guys. To help you with your deliberations, I can confirm that I was very delighted with the DMS re-mapping to both my GranSport and GranTurismo S. On the GranSport, I was getting about 430 bhp. That was confirmed on DMS' rolling road before and after the re-map. Where the real gains were in mid range torque. Top end performance was much better, and the rev cut out was raised by 500 rpm. One word of caution, the engine re-map does not tell the gearbox that it will now rev an extra 500 rpm! So if you were doing a track day, and going down the 'box, you may find a delay when the gearbox doesn't recognise such high revs!! It isn't a problem to worry about, but one to be aware of. Fuel consumption was no worse, but the engine did run a lot smoother. For the price, I think it is well worth it. DMS have done quite a few different cars for me now, with no trouble at all. The difference each time has been marked and amazing. If you do decide to go to DMS, bear in mind that Meridien Modena's service garage is 3 buildings down, and their wonderful showroom of Ferrari and Maserati is only 4 miles away in Lyndhurst. I can assist in organising that if necessary.

Cheers for that Barry, did you have any other mods done on the GS or the Turismo exhausts etc ,and did you say that the GT when re mapped was returning around 460 bhp , made me wonder why as its virtually the same engine as the GS and QP

Thanks Barrie,

It'd be helpful to run these dyno tests after a few weeks and a battery reset just to see if any performance is lost (or gained) with use.

Also, do DMS offer a single remap? Or do they tailor-make one based on the setup/mods individual cars have?

Thanks!

The GranTurismo S was pushing out 477 bhp. No extra mods. Same exhaust. When I went to Maranello to talk to the engine guys at Ferrari, they admitted that the Maser engines were detuned a long way to create a difference between the two makes. Mike and Rob at DMS recon it was very easy to extract the power increase. That also confirms that Maserati have to play ball with Ferrari on the corporate power levels.

Barring the MC12 of course , couldn't resist slipping that one in ,

Once the ECU is remapped on a standard setting that DMS have developed. I have had an Abarth 500 done by them which produced 190 bhp with the standard exhaust, then 197 bhp with the Monza exhaust. The ECU programme was the same. The only potential problem is if you go to a Maserati Dealer who wipes clean the ECU programmes and then resets. DMS will sort you out if that happens. Sorry, but I can not see how you will get a reduction of power after a few weeks. The engine works to the parameters set by the ECU programme. A battery reset will do nothing at all to the performance, unless i am missing something here!

What other mods have you done to your car?

This is now getting a bit more interesting as Barry's comments are very positive, more for the improvement in engine performance than the bhp. Still can't swallow 900 notes though.

Need a bit more convining myself yet Miles , but agree a step in the right direction, spoke with Matt about this and he reckoned to strike a deal / open day for 5/ 6 cars in one sitting and £2.5K-£3K for the day so a good hard days work for them and a result for us at £500 a pop what you reckon

Yes Loz, Barry's comments are encouraging, but additional endorsement would be welcome, and at 500 rather than 900 it would become quite tempting.

We'll have to see how good my negotiating skills are , as and when, keep an eye on the thread

So Loz, what do you recon we will be getting from the GS then. Its 400bhp stock, and we have the Larini free flowing exhaust and de cat, so that must count for 20hp so plus the 30hp from the remap, we should be pushing out more horses than a standard GTS. Now on another level, this makes me look at the the GT 4.2 again. Spend 2.5k on an exhaust and remap and you have a car that will technically be faster than its bigger brother.

What do you recon?

Hard to say Matt but it will be very close, my thoughts, we need a test pilot ,

Hum, food for thought though.

Ill tell you what, I will be up for this remap to see what we can extract from the 4.2 to make the GT a better proposal.

I can justify spending twice the amount that the GS is worth for a car that feels, well, sluggish......progression, it needs to be at least as fast as the car I am selling. The day I start going backwards, is the day I give up!

But it looks as if you're all going in the right direction.......will watch with interest, especially to see if Loz........can work his magic!
