If anyone tries out this new piggyback by RENNtech on the CLE53 let me know! I think it's relatively new, but looks promising. Feel like for a plug and play device it's on the pricey side though. I remember other plug and plays were more around the $600-$700 mark.

Any one have experience with them yet? Might be to early to ask but wanted to start the thread anyway!

Thank you for the link, good info. HOWEVER, I ran some numbers and the Renntech HP/TQ numbers just don't add up.
I've been waiting for engine dyno of the CLE53 but their own Dyno curve numbers don't agree with what they state in the words below.
Curves, Stock: 414HP/435TQ vs Words, Stock: 493HP/517TQ
Curves, Chip: 455HP/470TQ vs Words, Chip: 541HP/571TQ
Curve Chip-Stock: 41HP/35 TQ vs Words Chip-Stock: 48HP/54TQ
I am very pleased with the Renntech stock rear wheel dyno numbers. I have heard that MB/AMG under-rates their engine power but there is a lot of confusion between Power measured at the engine vs the rear wheels. I have to think that MB rates their engine power at the engine, with no drivetrain losses, and the Renntech dyno is rear wheel only, so the M256 looks really good. The math using the Renntech words adds up, the difference between the Renntech Stock Dyno and the Renntech words is 19%, which is more than the 16% Renntech claims to use to compensate for drivetrain losses. And if both numbers are rear wheel then I don't know where this power increase comes from.

I think that the dyno curves are accutate and 41HP/35TQ gains are reasonable for a mild tune with increased boost and the accompanying fuel and timing mapping. Power you will feel but it ain't 541HP/571TQ no matter which way you calculate the numbers.

P.S. 414 RWHP translates to 480 Engine HP using a 16% drivetrain loss, pretty good!

Right! I hear you. I was also confused on the numbers and how it's calculated. I think your maths is good and seems right. My goal for the car was trying to hit 500bhp so this could take me almost there haha. Just costs a **** ton, when other piggy backs seem to be way way less. Would you be tempted to try it? Maybe when there's more options it'll come down on price.

Thanks again for the link. I did a quick look at other Renntech chips and the pricing is in-line. I think increased IC chip prices have something to do with the high prices.

My biggest concern with having the chip is how it affects the car warranty. Any drivetrain issues would give the dealer an excuse to say, "that's not covered, you modified the car with a chip". With all the electronic monitoring in these cars, I think they would know.

Number 2 is, that seems to be a lot of money for less than 50HP. There aren't many cheap mods for these cars. To get to 500bhp, and to do it right, you'd need the chip plus a full exhaust, from downpipe back, and a custom tune. None of that is cheap. If you're going racing it would definitely make the car faster. How fast you want go = how much do you want to spend. The car is pretty heavy too yet I ran 12.01 in the 1/4 mile with my car (that performance supports the higher-than-quoted power numbers). That's a great number, but of course now I want to be in the 11's, lol. The cheapest way to improve your 1/4 mile performance is to work on lowering your reaction time.

The good news is the stock engine performance. Over 400ft-lbs of torque from about 1800-5300rpm. That's huge! That's like big block V8 numbers. Area under there curves is more important than peak numbers. The chip definitely bumps that up and raises the rev limit too but I'm going to hold off for now.

Very true! I've had chips on previous cars, albeit not a Benz and anytime I had issues I removed it and took it in for warranty work without any questions. It was never anything to do with the actual module though but they definitely deep dived on a bunch and didn't say anything or notice there was a piggyback installed. You're still right though, every manufacture is different and might not be worth the risk. Im also gonna hold off too!

Bro, 12 on 1/4 mile is so so good. You done any measures on the 0-60 yet? I keep hearing 3.8s floating around. I love this car and can't wait to reach 1K miles lol.

Super crazy for less than 50 HP gain. BurgerTuning took a look at my car, through pictures, and said their tuner will work. Less than 800 and you could get a lot more power. Worked great on my Audi.

Thats what I was thinking, had that tuner and Madness before, way less money. You have a CLE53? They said it would work?

yes, they had me take the cover off and send pictures. They said it would work.

Oh nice, that's really good to know. Might wait till they have a specific one for the CLE incase there's any small adjustments. Unless it uses the same as E53 or something. But might wait to be safe!

Imagine paying $2500 for a Stage 1 tune....no thanks

I emailed Burger and they said they needed pictures of the plugs. Sounds like You already did that and they said yes, they had something for the CLE53?

Yes they said it was compatible

Nice! Anyone see anymore options drop them here. I just seen RaceChip brought out one specific for CLE53, but they always get a bad rep over the other options from what I've seen.

Does anyone here have the RaceChip, BurgerTuning or any other tuning module installed on their car? And if so, does it do what it claims to do?

I see race chip just dropped their official CLE53 tune. Might have to try it!

Dropping the Race Chip link here 👀

I had JB4 on my old E400 coupe. Great piece of kit. Just installed the JB4 on my new 2025 CLE 53. No other engine mods at the moment.

I'm tired as s...with the time change, so I just warmed it up in the garage, changed it to map 3 (+6 psi) and gave it some revs. The exhaust seems louder with more burbles, etc., which goes against what I would've thought with more boost. Going to get a tank of E30 tomorrow, run it through its paces and report back.

Which JB4 works with this CLE53? You using this one? I don't see an official CLE53 one yet.

That's the one. There's very little to no difference between the latest 53 motors: motor code M256. Same engine in (I'd guess) all 53 models. Saves auto makers a ton of $$ to standardize things across product lines.

There's a good chance Burger might not even update their site showing it works for the CLE because it's the same motor as w/almost every other 53.

~3 years experience with the JB4 on the E400 (M276 motor). Never once a hiccup.

Amazing! Thanks for clarifying man, may have to test it out. Had other piggyback tunes on other cars and had zero issues.

How hard is the install? Does the guide on their site apply to the CLE too, roughly?

Keep us posted on your experience with it in the next few days!

Good ol’ Juice Box!! I had the competitor piggy back on my E60 bmw 535i, vishnu procede, but so many people swore by the JB4. I’m also keen to learn how tricky the install is, if PC required for updating/logging, and of course how it drives!

Burger has installation instructions for each model. Your install will of course vary based on how much you've wrenched in the past. My car has a front strut brace, (not shown in the instructions) which I highly recommend removing as your first step...4 bolts. Otherwise, the instructions are pretty straightforward. You're hooking up two connectors: one MAP Sensor in the intake manifold (red/yellow JB4 wires) and the second in what looks like the throttle body itself (brown JB4 wires).

I took my time because I hate having to go back and fix missteps, and it took me maybe an hour? And that's with running the OBDII wire into the engine bay/the JB4 unit, tidying everything up, etc. Basically making it invisible.

Oh, and to the last poster...I use the JB4 app on iOS. Switch maps wirelessly on the fly, boost by gear, etc. It's 2025

Sweet thanks for that info. Now my next challenge: Trying to buy one and get it delivered in California lol.

? Burger ships from SoCal. Or NorCal...I forget lol but they're in your hood

The issue is they are not allowed to delivery in CA because of restrictions/regulations ...even though yeah, their office is based there lol. Was only just emailing them.
