Why so many people having issues with stages 2 lately? I have stages 1 with problem free so far. In my opinions, stages 2 is not worthy for me. You spent 3x more $$$$ for just 30-40 more hp over stages 1 and lots of headache with misfired
Well most people come to the forums because they are having issues with their cars and seek more opinions on the issue. You are seeing only the people who get stage 2 tunes and have issues. Out of all the c63s and e63s owners that I know, I am the only one who has had issues with their car after getting a tune + downpipe. Additionally, I am the only one who uses mbworld out of all of them.

agree man.....
stage 2 is a mad fckery in total i've seen 3 guys posting about blow their engines on the aussie c63 group on facebook both stage 2 both tuned at international autohaus the other one tuned stage 2 off the shelf.......
looking more into it these guys mentioned injector failure cause piston to do something blah blah.........

DON'T DO STAGE 2
WOW … that’s the first time I heard of engine blown. Most people reported of misfired from stages 2.

I feel like these issues all stem from pushing the envelope on a car with deferred maintenance. Either that, or off-the-shelf, one size fits all tunes. That may work fine for a "Stage 1" tune, but as things are pushed further a custom tune to the specific car is needed on order to be safe.
That's how I got my motorcycle tuned, on a dyno with a professional who knew what he was doing, and I've had no issues. I'll definitely be going that route with my much more expensive to fix C63 when the time comes.

3 guys from the same tuner, sounds like a tuner problem. Who knows wtf that tuner is doing. Doing my research I’ve seen some tuners pushing it way too hard just get a high peak number vs tuners that are more conservative and keep it steady throughout the RPMs.
I’m having problems with misfires and some other members as well but it generally sounds like a small problem to fix. I’m the second owner so who knows what fuel quality the first owner used. Its not like we are out here breaking axles or blowing transmissions left and right. Just need some injector cleaning, maybe a fuel pump and some new sparks.
but I think you're overreacting a lil…

Hope you all sort it out soon before your engine blown up due to lean running conditions. Some owners changing everything like spark plugs, coils … etc. and still unresolved.
I don't really understand stage 1 vs stage 2. Does stage 2 require additional modifications? or is it literally a more aggressive tune without other mods? I came from the STi world where stage 2 was downpipe and tune. Stage 1 was tune alone. Intake was just thrown in there somewhere. Fuel upgrades typically came along with stage 2 because you started running out of fuel with additional air flow from turbo.
I have the Renntech HHT. Is that considered stage 1? They don't even have an option for stage 2.
They have the "regular tune" and the "intermediate" tune which they recommend for 91 octane fuel locations.
So back to my original question. Is the regular Renntech HHT tune stage 1?

Stage 1 - No hardware required just factory car with or without AMG Performance exhaust.
ECU is then tuned (TCU tune not required with Stage 1 at all but is optional if you want a bit more torque).
BMC panel filters are an ideal upgrade too but not required.
Stage 2 - You'll need Downpipes + Intake (minimum) for Stage 2 ECU & TCU Tune to be done.

Yes there's been a few M177's blown from stage 2 here in Australia. I've seen three or four so far on social media as well.
Bit concerning aye but most likely a tuner issue as all cars I've seen have come from the same garage.
Personally there's not much need for anything more than stage 1 and 600hp at the crank. Even stock power is quite brutal.
I don't even know why you'd need more than 600hp in this car with all the traction issues anyway.
I'm happy with mine at stage 1. As noted, stage 1 whether off the shelf or custom dyno tuned is the safest out of all tunes for these cars unless you're going all out with a proper rebuilt etc etc

Reason: Added some more details
My understanding is you can put dpwnpipes on these cars and not tune them (sound only from what ive read)....whether stock or stage 1. However if you tune a car with downpipes, its considered stage 2.

Is that accurate?
Thanks
You can as long as they aren't catless downpipes or you'll throw a code. But if you really want to go catless downpipes without a tune and you don't mind having that Check Engine Light glaring at you, then sure.
You can get the CEL coded out though or use O2 spacers.
If you don't want to tune, best to get catted downpipes. Less cabin smell, too.

I appreciate your input.
No plans now to go any further then I have, but I've toyed with catted DP for some sound. Just not sure its worth the cost and possible headache.
Your Catless DP 1300 with labors? Hell no !!! For about $1500 stages 1 with 30-40 hp less and no headache. Personally, it a smarter decision.
I did it myself, 3-4 hours of labor with jack stands, basic wrenches, and a saw. It was pretty easy but I have rebuilt engines and supercharged cars in the past. My car dynod at 500whp without DP. It was a significant gain.
