So I have some news for the group regarding the tune. I called my local Eurocharged shop this morning and talked with the guy who answered the phone and he was a very nice guy and also very straight forward and honest with me which I appreciate! I explained to him that I regularly drive the car 250 miles each way to work and that it is a 2018 with 14,000 or so miles on it. I told him that reliablity was the 1st priority for me and then he explained to me that if that was the case there are some factors that I should consider before tuning the car that could play into my reliablity factors.

1. He told me if the CPC module is not replaced with a new one and then tuned, that the car would go into limp mode at some point, he said not IF but WHEN. The cost for a replacement tuned module is $2500 on top of the tune for $1300 + 299 for the loader to keep with me.
2. The guys said, "if we tune the car, without doing anyting with the CPC module, it will give you issues." He said if your gonna tune the car and want it to be done right and reliable then you have to do both, otherwise I would leave it alone if you depend on the reliablity of the car.
3. So now I am at a crossroads, he also said the top speed limiter would likely not be increased also which is a big factor for me as currently the car sits locked at 130 MPH WHICH sucks! The CPC module replacement and tune is required to lift that restriction as well.
4. Sure seems like a lot of cash for an additional reliable 90 - 100 HP.

It sure would be nice if we did have someone who has tuned an 18 E43 that could chime in as to what they experienced, I am slightly more gunshy now to the process as again, I need the car to be reliable. We also discussed a mild tune on the car which would likely not experience as many limp mode instances, but hey if your gonna do it, why pay for a little bit!

Any comments are welcome here!

If you do go with E43, get a stage 1 ECU tune to wake it up a bit and call it a day. If you are looking for speed, E43 is the wrong platform.

You are perfectly safe using that. Also on a side note, today i took the E43 to work (a 40 mile one way commute) and averaged 28.3mpg at 75-80mph compared to my wife who was always getting around 22-23mpg same distance/speed. Not sure if this is supposed to improve mileage and YMMV (lol). I am pretty happy with the tune, the car definitely feels much smoother and nimbler when accelerating. Congrats on the E63, I wish i were that rich

My apologies, I have been talking to Eurocharged, and that is who told me that with a CPC tune only that the car will go into limp mode and throw codes and become inherintly unreliable and that the TPC tune was almost a must have. How long have you been running the flash? How is the reliablity? Any lights on yet? I decided to break down and buy the 23 E63 because it is the last year of the V8 so I figured it would appreciate and if I kept it low miles and locked away in the garage. I am curious to know more about the Eurocharged tune and how its acting... Please share more and also any dyno numbers they may have given you...

He shared with me that i only needed the ECU tune and nothing else was necessary. He also stated that the reliability would be untouched vs stock, as in the car would be just as reliable as without a flash. The TPC is only needed if you want more power/faster shifts and if you "get on the car" a whole lot. For my use case, this is my wife's daily commuter and she isn't going to be abusing the car much (hopefully lol) so i suspect it would have the same reliability if you treated it the same way when its in stock form. That said, if you beat on it when its stock it may also be less reliable and more prone to having issues early on. We currently have 45K miles on the car, the tune was literally just flashed yesterday and have since driven only 100 miles so far. No noticeable differences other than what i mentioned about mpg and responsiveness so far. No lights or anything, was a fairly easy process. BTW i got a deal from Sean so PM me if you're interested in some tips.

As for dyno numbers, i don't have any. Eurocharged claims a 480hp crank number compared to the 396hp stock number. I will say my butt dyno def feels a difference lol. With that said however, i will be checking some 0-60 times using the Torque Pro app here in a few days to see if its faster than the claimed stock timings.

If you need any help or have any questions, i may be a noob but i am more than happy to help address whatever questions you got. We are all learning together. If anything breaks or goes bad i'd be the first to mention. I will also add that i plan to do oil changes every 5k miles and spark plugs every 35k miles.

One thing is to buy it, but another thing is to maintain it over a longer period of years. Yeah the V8 BiTurbo sounds a lot better, don't get me wrong, I would have done the 63, if I could justify it. But I got plenty of other things to spend the $40-50k on. I am referring to the E63S wagon, I know they are $10-20k more than the sedans, but that's still a good chunk of money.
