I have a 2008 w211 e550.

I have a muffler delete and would like to do the oe tuning and add high flow air filters. I understand I won't be making huge gains, but how much power would I roughly be looking at making. Oe tuning says a 25hp increase with the tune. Would I be looking at around 415hp?

Thank you.

I have a w211 e500 4 matic wagon. Muffler delete, high flow filters, no cats and a race iq tune. Should be good for 20 hp to the wheels. Need a awd dyno. Feels totally different. Leaves a light like a animal.

with a tune you cant just look at peak HP ratings. it is more about what is does to the curve. you are almost never at peak HP

Very true. I'm looking forward to a dyno session at some point. So I can actually see what it puts down.

honestly i dont think the mufflers or filters will really add anything, maybe 5hp over what the tune does.

Yes I agree. I installed them for the simple fact that I can clean them. Plus when i bought the car. The air filters look like they were never changed.
