Smooth tuning experience

I ordered an "effektøkning" for my car last month. The booking process online was straightforward, and I got a confirmation email quickly. It took 5 days to reach the DMax center in Oslo, which was fine. The technicians were professional and explained the process well. The quality of the tuning seems good, I've definitely noticed a difference in power and responsiveness. Overall, a good experience and my car runs better now.

Car feels livelier

Got a "gasspedalrespons" upgrade. Didn't take long at all. Car feels a lot snappier now. Happy with it.

Good value, solid results

I was looking for some eco-tuning to save on fuel. Found DMax, and they had a "dieseloptimering kampanje" going on. The price was competitive, much better than some other places I checked. The actual tuning was done efficiently, and I've started seeing a small but noticeable improvement in my fuel consumption. Worth the money for sure, especially with the discount.

Is DMax tuning easily detectable by a dealership if I bring my car in for service? Don't want any warranty issues.

A Amber M. 3 months ago

It's always a risk with any tuning. Some tuners claim it's undetectable, but modern dealerships have pretty advanced diagnostics.

E Emma 3 months ago

i think it depends on the type of tuning you get. obd tunes are often harder to trace but if you get a full ecu flash, sometimes they can tell. best to ask them directly, but they usually have options for that.

Can you actually get a refund if you're not happy with the tuning results from DMax? Or once it's done, it's done?

C Cleo Walsh 2 months ago

I think there's usually a trial period or a satisfaction guarantee, but you should check their terms.

D Dan V. 2 months ago

Yeah, I'm pretty sure you can reverse it if you're not satisfied within a certain timeframe. I remember reading something about 'angrerett' (right of withdrawal) for tuning services. It's not like you're stuck with it forever if you don't like it, they usually have a policy for that.

How do DMax compare to someone like Bestchip or Optituning? Are they really that much better, or is it mostly marketing?

A Andre 2 months ago

I've heard good things about DMax, especially for diesels. Bestchip is decent but DMax seems to get more praise for actual gains.

R Rachel 2 months ago

Hard to say 'better' definitively, as it often comes down to individual car models and what you're looking for. DMax generally has a good reputation for reliability and solid gains, and I've heard they have good customer service if you ever need tweaks. Optituning is also popular, maybe slightly cheaper sometimes, but I went with DMax for the peace of mind.

Anyone know how long the chiptuning process actually takes at one of their locations? Trying to plan my day.

R Rosa Vargas 2 months ago

From what I remember, it wasn't super long, maybe an hour or two for a standard tune? Depends on the car though.

D Derek M. 2 months ago

Yeah, when I got my dieseloptimering done last year, it was pretty quick. They usually give you an estimate when you book, but for just a chiptune, it's usually in and out the same day, like a couple of hours max.

Do these guys ever have Black Friday sales? Or should I just jump on the current 'kampanjetilbud' for dieseloptimering?

K Kevin C. 2 months ago

They definitely do Black Friday stuff, usually pretty good discounts on specific packages. I'd wait if you're not in a hurry.

B Beth Silva 2 months ago

Yeah, they have seasonal campaigns, Black Friday is one of them. Sometimes it's a fixed amount off, sometimes a percentage. Current offer might be good but BF is usually bigger.
