Wait for custom tune via HP tuners or go with EC mygenius??
- Do companies/tuners on the forums offer something like EC v7 can tune for hp tuners device or something (not even sure what to call it)?
- For an extra 200 bucks, I think it makes more sense to just wait gather my mods and get a custom tune for the car rather than figuring out how to get EC to give me a custom tune for like another 500-1000 (correct me if I am wrong on this price) via mygenius and finding a shop, having to pay them etc. just sounds like a headache and more money but I might be ignorant of how it all works so any advice would be great.
Car is currently stock right now but I am slowly gathering mods together. Already bought row airboxes, planning to get headers probably in a couple of months, then flex fuel with upgraded injectors. Or am I completely wrong with how I am thinking about the EC mygenius and I can just buy this thing once and EC will send me updated maps in regards to my modifications for a certain price which outweighs the benefits of just going custom tune a couple of times? Btw, I would love to tune my car now with the row airboxes and I have funds to do it but I am trying to make the best financial decision and not regret it later. Any advice/experiences would be great with either options.

HP tuners will allow for tunability, but a tune from the likes of OETuning, Eurocharged, RaceIQ, etc will ensure your car will run and drive. Their tunes are based off stock mappings, so they're guaranteed to work for the most part.
You really have to weight your goals and what you plan to achieve.
I JUST got a Eurocharged Tune and a MyGenius Handheld so I can go back Stock in 5 minutes anytime I want. I loved my Tune. No issues and still drives great actually even smoother than stock.
If your car has LOTS of Mods it may be better down the road to do a custom tune as your car will have a lot going on and they can drive with you in your car and data log to get everything perfect like your Air/Furl Ratios etc.
But EuroCharged has done hundreds of Mercedes C63’s and they know what they are doing and if somethings not right they are good about fixing it.
Mine was fine fine but I had a minor issue loading a Tune and they took care of it, so I trust them.
Good Luck.

These cars are not easy to tune go with a backed brand go with eurocharged 100% at least you will have plenty of support if **** goes pear shape




If he does not have a base tune then $1K is too little.

customer service is spectacular and questions usually answered in hours at most.
in many states it is also very helpful to flash back to stock before emissions testing as many tunes deactivate some oxygen sensors. For this, flash back at least a week before testing and use an ODB to check that all is reading once the cycle completes.

Regardless of the tool used, a thorough custom tune done well will always be better, safer, and produce more power/torque than a generic solution.
For every workshop or tuner saying "I'm always fixing <insert tool/company here> tunes/work", there is just as many saying the same about that company.
i can tell you that the eurocharged tune drove weird with shifting and tb wouldn’t open past 70%. Very rubbish tune. With timing crashes passed 6k rpms.
i tried to get a hold of Jeremy to get to his tune. But he wasn’t in country anymore and I had lost faith after something’s ive heard and read about them.
i went with HPTuners. I’ll tell you now the parameters are a little confusing. User friendliness I’d give a 7. Ive spent nearly 3-4 hours dynoing and 3+ street tuning. I built the map from ground up and I had tuner verify my progress along the way.
