Mercedes diesel chip tuning box ML 250 220 280 300 320 350 CDi performance

E350 sport Estate

We what can I say???.
It takes just minutes to fit looks nice and compact. I can only think of of saying OMG 👌. I've noticed the change straight away. It's revs at a lower output the acceleration is unbelievable and I'm very happy with the fuel return already. Yet to try it in sports mode but if economy makes me smile then sports will probably s##t me up. You've got to try one yourself to believe me. I've had different ones on many cars and this has got to be the best yet. Brilliant. 😊Read full review

Pleasantly surprised

If like me you are sometimes skeptical about the reviews that are sometimes left, please rest assured this one tells it as it is!! This is quite simply a fantastic little box of tricks. I have used tuning chips in the past on various vehicles from different suppliers, which can sometimes be unresponsive, but this absolutely knocks spots off them!! There is an instant noticeable improvement in the torque and performance of the car. It is far more responsive, and seems a lot smoother too. I haven't had it fitted for long enough yet to be able to gauge the economy side of things, but if it is anything like the increased performance then I will be very happy. It leaves you with a big smile on your face every time you put your foot down!! Feel far more confident now overtaking, knowing there is the power there to get you out of any tight spots. Very easy to fit. Takes about 2 minutes for someone with little knowledge of engine layouts. I cannot recommend this product highly enough. You certainly won't regret it if you purchase one!!!!Read full review

Fantastic piece of kit!

I bought this tuning box recently as I wanted to liven up the response in my 2014 E Class.
It was a pleasure to fit and the phrase “Plug and play” is definitely the most suitable description of this unit.
As it’s a UK box the instructions are clear and simple - no Chinese pigeon English translation here!
The manufacturer even included a colour shot of the engine bay on the Mercedes for easy identification of the fitting plugs. It all made for a confident fitting procedure which took about 3 minutes!!
Read the informative directions first so there’s no problems.
The most difficult part was popping the plastic engine cover over the engine 😜.
Unlike a lot of foreign after market components this was a quality well designed item that can be installed and removed in minutes.
On a performance note it delivers instantly.
First impressions were fantastic . The sedate E class 2.2 is now a lot more responsive and lively car especially when overtaking and accelerating.
Don’t let the reasonable price put you off. It’s as good as any tuning box twice or three times it’s price.Read full review

Merc E320 cdi

I was a bit sceptical about any tuning chip box, so thought I would give this one a try, after reading reviews, which seemed to rate it highly, so I gave it a go, and to my surprise, I noticed a difference straight away. My E320 cdi picks up better is more torquey and achieves about 2-4 miles per gallon more. I'm not a fast driver and strive for economy, but I would recommend this box based on my own experience.

Simply an amazing improvement.

Adds new verve to the driving experience whilst the engine runs more freely and smoothly. A discreet fitment; removable too before selling the car....
