EXE Digital Tuning

Faulty chiptuning and utterly NO CONTACT with them. They've got at least three websites, FB page (Drake Box, the same company, same address) with no option to talk to them. I sent the chiptuning back with tracking mail, still no contact, no replacement, no refund. Stay away from them, even if some of your friends bought it and their chiptuning worked, you may not be that lucky.

Didn't see the negative reviews until I had the tuning box purchased.
Anyhow, worked perfect on my car (520d e60,177hp) and turned it into an animal on the road with good fuel economy as there is loads of pull even in 4th gear at 1k rpm.
Can only recommend for same type car as they have obviously sent me a tuning box with processor rather than a resistor in a box.
(if anything changes over the next week, I'll be back to edit)
Update! Have the box installed about a week now & still happy with power increase... mpg calculator seems to be telling little lies as I'm getting about 100 less miles per tank but what do I expect when I keep flooring it. There is a dial and switch inside box for changing perameters if one is not happy with initial setting.

I get my item delivered quick although the instructions did not match with the car itself. Tried to contact and sent emails 5 times, nothing they always closed the case without any reply. Poor Customer service, requested refund no info in return.
If you want waste your money, go ahead and buy from them.

I put this on a an 1.6 90hp VW/Audi diesel engine. GOT alot of more torque and its like a new car. It added the little extra. I was sceptical. But devisen to try it. Read the manual and follow the steps this is hos you avoid warning lights. It has to be setup like the manual says. I har 40 000+km on the box still noe issues, black smoke or start/idle trouble. Its cheaper Than oljer companies and does the same job.

J'ai commandé un boîtier additionnel sur ce site je n'arrive pas à trouver le connecteur je leur ai écrit plusieurs fois sur leur site ils ne m'ont jamais répondu il ferme mes conversations sans me répondre incite à fuir si vous êtes français ne pas commander sur ce site car il n'y a pas de service après-vente et jamais aucune réponse

I brought a tuning box for a Renault diesel car. It was fitted by my local tuning garage. The car went like stink but when cold started all the car warning lights went on and had to be reset by the garage. Tried to ring them, answering machine telling me to email them. Emailed them from several email addresses, no response. If you are thinking of buying one, then good luck... there is no support.

I brought one a few months ago which caused the car warning lights to go on. Couldn't phone (just a recorded message) them and they didn't respond to emails. DO NOT BUY FROM THEM!
