Modifications tunes?

I have a 2025 ClE 53. It’s at Renntech now getting some coil overs, blow off valve, axleback exhaust and a downpipe….
I’m trying to wake whatever Amg life in her up a bit.

Has anyone done any other mods yet or Tuning?

Can't wait to hear your feedback! You mind sharing how much the mods cost all in? I know the tune is not cheap at all haha. But really excited to hear your experience. Especially the DP and axleback. Do you know what DP they're installing? I've seen a few online.

I'm adding a JB4 later in May and a downpipe. If it comes a bit more alive with those alone, I'll probably leave it at that mod performance wise.

Im assuming the Jb4 is like the version Renntech has? Or is it for the older 53s and possibly compatible?


a lot of it is still R&D so I don’t really have a price… more of an estimate. They haven’t done a lot of work on the cle 53 so I’m the guinea pig lol.

what I do have is -

Coilovers 1700$ (labor intensive)
+ alignment Total 4k

blow off valve 1000

axleback exhaust 3k + labor

downpipe ?

power module ?

im assuming all in all it will be around 15k?


also I ordered this spoiler lip thing from maxton design it looks good but it’s coming from Europe. My expectations aren’t too high lol

Here is what I have done to my 25 CLE 53 thus far. JB4, BMC air filter, down pipe, wheel spacers, maxton rear spoiler, tinted windows, changed all the badges on the car, changed front benz emblem to all black,



blacked out door handles & rear reflectors. Last but not least the car has been ceramic coated.

Looks so sick bro!! I love it. Did you notice a big diff with the JB4? What map are you running?

Also if you have any videos of your car with the downpipe, i'd love to hear the difference compared to stock. Which one did you install?

How much faster is the car after all these modifications and has it added any horsepower or tourque?

yes the JB4 certainly is making a difference in map 3.

Nice mods! I have been looking into that Maxton rear spoiler but have not seen that many examples of it out there.

Which downpipe do you have? Would love to hear how it sounds.

which version of jb4 did you get? There’s two different selections. Also did you get it with the wireless kit option or the bcm cable option?
