the only company that offers it here is digital tuning and this is what they offer

torque increase is scary...

definetly! or use a tunit box... www.tunit.co.uk power increases aren't listed for the new 330d but they do offer healthy increases... I would expect 270 bhp and 430 lbft torque from one of them. Or get someone from DMS to fly out to you? lots of companies and choices to choose from.

dms would be nice but the cost would be skyhigh... cause they gotta come with all their equipment

true... The good thing about the tunit boxes are that you can add them and remove them to various cars, so when its service time bmw wont see it or you change cars (diesel) just swap it into the new car. plugs in.

so can i plug it myself ? or does it need to be done in a garage

525dse

Plug it in yourself, and on some units you can increase boost or decrease it This is what my friend said to me, when he ordered one for his 307 2.0 hdi.

quote from the website...

"Every Tunit is designed to be compact and lightweight, the smallest being only 10cm across, the largest being 13.5cm. In most instances the Tunit comes complete with original manufacturers plugs and connections. An original quality harness to fit in-line is also provided. Most Tunits are fitted in 10-20 minutes and all are designed to be easily installed by people of average mechanical capability. If you prefer, we fit the Tunit for you. Fitting is offered by our international network of world wide distributors. Fitting is usually carried out in less than 20 minutes Fitting at any of our distributors does include a try before you buy so as you can be assured of the performance before you purchase. If you wish to remove the Tunit for either fitting on another vehicle or for any other reason it is just as easy."

performance...

"All Tunits are specifically designed to achieve enhanced diesel performance by modifying the fuel injection parameters and only by the careful interplay of these values and characteristics can the optimum performance of your engine be achieved. The turbo boost pressure is not directly altered (on turbo models) by the Tunit and is only increased via the natural increase in exhaust gases provided by the increased performance. The design and development of the Tunit has come about by the collaboration of some of the top minds in Europe and is the latest and most advanced device available on the market today. Our ongoing development programme ensures we keep up to date with the latest engine management and injection systems."

adjusting power settings...

"Manual Adjustment - All Tunits are adjustable in one form or another. This allows the Tunit to be individually matched to each and every characteristically different vehicle. This can be very important as two cars the same may not react and drive the same. i.e. one VW Golf 110 bhp may produce 105 bhp, the next Golf built on the same day may produce 115 bhp. For this reason we have built in simple methods of reaching your optimum performance.

The Tunit V-CR, V-PD and V-VP models come pre set for the vehicle.Each Tunit has a 9 position rotary switch. Each position will provide a different power level. 1 is the lowest, 9 is the highest. The Tunit II, III and IV also have a manual adjustment and require a simple adjustment on installation to the vehicle."

needforspeed

Slightly weird - DMS have advised me that they could take my M57 3.0l deisel from 218 to 260hp (much greater increase in peak HP than for digital tuning), but torque is 'only' increased from 500nm to 570nm.

The torque figures from digital tuning look amazing in comparison.

0700700

i know.. they always offer massive increases in torque

e.g. for e60 m5 > from 510nm to 589nm
for Mercedes e420cdi > from 730nm to 950nm

and for the 535d a more reasonable 711nm
