Stage 1 GLC 43 0-60 3.8?
First question is... is the onboard/OEM calculator accurate if wheel/tire diameter is unchanged? I'm eurocharged stage 1 and the track 0-60 is telling me I'm getting 3.8 which is .9 faster than stock. That can't be right?

Are you getting consistent 3.8’s or was it a one off ?
I would think that just with a tune you would only get a few tenths off. Maybe 2-4 at the most.
Did you only do a CPU tune or TCU at the same time?

Cpu and TCU. Man, I've seen a couple 3.7's... but 3.8/3.9 is normal.

I'm in the same boat. My wife drives it way more than I do. She leaves it in moderate and she's good with it. Mine is lowered too so it's a little rougher than normal because of that. But she doesnt complain.

Just to double check, you have Eurocharged ECU and TCU tunes? Not the CPC?

I just had to go back and look... I was wrong. It has the ECU and CPC tune, not TCU.

Okay, thanks. I think every tune got mentioned so it got confusing. But ~3k in tunes to get to 0-60 in the high 3s? The AMR CPC replacement module is like 2.5k alone.

Yeah, all of it is over priced for off the shelf tunes... but it is what it is. I still think dropping nearly a full second to 60 is quite significant.

Nah, I'm in agreement it's good value haha. Also, lastly want to ask if you used a handheld or if you took it into a shop for the tunes?

Initially I took it in. They did the initial tune and put the cpc in. But I did get the dongle so I could flash back to stock before taking it to the dealer.

Now that I'm out of warranty... im probably getting dp's and going stage 2.
