Has anyone heard or know of tuning company

They have a PowerBox for turbo diesels, are they any good? Pros? Cons?


Thanks

Steven

I have also heard that Kleemann makes an KD Box for MBZ diesels.

Anyone know if they work for the W210 E300 TD?

Any experience?

I have an Upsolute power chip in my 1998 E300td. It makes great power and drivability. I have had it for about 6 years with no problems. It smokes a lot more under full throttle but only uses more fuel if you use the extra power.

Hello,

I have a customer that has 99' 210TD chipped by speed tuning usa and he loves it. I have driven it and it pulls very strong when the turbo finally spools. However, there is quite a bit of black smoke when at full throttle. It should be expected though since more fuel gives you more power. He has had it on his car for about 2yrs now and almost 30k miles. He says that the fuel mileage is still the same when he is not going crazy on the throttle. No problems have came about from it so far.

I work at a dealership that installs Klemmann performance parts and there are no chips available for a 210TD from them. I am planning on chipping my 99' 210 this spring with speed tuning. I believe it is the cheapest chip on the market and they also have a 30 day (believe it is 30 day) return policy. They can remove the chip it you are not satisfied. Hope this may help you and good luck with your chip choice!

More like 50K and no problems. It doesn't seem as smokey as before and I can only theorize as to why. It may be none, some or all of the below theories.

1. Leaky injector that was fixed recently

2. ULSD

3. Cold air

In theory I have got 33 mpg with the cruise control on and at 85 mph. Not admitting to anything.
