WANTED!!

I'm getting ready to pull the trigger on a tune for for my 2014, and it just so happens Kleeman is 20 minutes from my home.

It's funny to me that Kleeman tunes haven't really been much of a topic around here (or RaceIQ). However given their proximity, and their international reputation, I'm considering them. Not going with down pipes or catless yet (yes I know I'm leaving power on the table).

But I'd like to hear from guys here who've tried it. Do you feel the Kleeman tune was good or did you end up switching? Any problems with drivability or support? What about spark plugs; do they do well with the oem plugs or is this tune better suited to a colder plug?

I do, but I find it odd that eurocharged and ams tunes tend to be the dominant conversations. Same with weistec.

No one really talks about Kleeman tunes much.

+1 on Cory and Kleemann. Top CS and top product.

Is there really any difference between a Kleeman tune/eurocharged stage2/ams tune?

its like... well never know.

WANTED!!

Um........ok.🙄

Amg63-

so do you know if there’s a difference? It was a legitimate question and would love to get some info if anyone knows

There used to be a difference. Kleemann and Renntech were the leaders and many others copied or used their maps as a baseline. Now there’s very few if any secrets to make any one of the main tuners better than the others. Not that it means anything but Kleemann is still tops in my book.

Amg63-

thank you, just like I thought.

I noticed for example, the ams alpha tune and eurocharged stage 2 ecu tune, are advertised very similar, and with near identical power figures/performance so by now they are all likely doing about the same thing as long as it’s a reputable tuner company.

My apologies. The timing and nature of your question happened to coincidentally coincide with what became a "colorful" pm conversation with a certain vendor who shall remain nameless concerning tune comparison. I was initially wondering if this was about to become a carryover of that conversation.

When it comes to power gains, the majority of the "off the shelf" tunes are fairly similar. But there are a few characteristics that are different that just by showing different dyno graphs won't necessarily show you unless it was an overlay comparison. Even then, it's not a perfect comparison unless all things were equal, like being on the same car, elevation, temp, fuel, etc....In short, same car same conditions in a lab. Otherwise, engine temps, spark plug longevity, fuel consumption, and driving behavior not shown on WOT dyno at loads and speeds those plots don't show but would experience while driving under different conditions while driving where there are distinct differences. Depending on what it is you're looking for, you may have to have a conversation with the tuner to see data specific to those wants, and they may or may not be able to answer you.

That all being said, so far as I'm aware, for the majority of average consumers the off the shelf tunes from all of the tuners here perform as advertised and will be fine provided you follow their recommendations associated with that specific map they provide you. If you want more, you'll either have to dig deeper like I did and figure out whose tune does what you want, or go with a custom tune specific to your desired wants through the tuner you are most comfortable with.

Amg63-

in still trying to research the off shelf tunes to see the differences.

Ideally, if we had track times in similar conditions, to compare between the different tunes, I think that would be very helpful.

WANTED!!

You'll find a few on here, but you'll find a different problem of differing driver skill. You'll also find it is with differing car setups. You can at least get a rough idea though as their drag times definitely improve.

Amg63-

i can’t find anyone who tested the eurocharged stage 2 tune at the track!

did you by any chance look into different track results from different tunes?

im thinking, would be cool to compile a “list” of the average times. Anyone who can also help, would be great info for us all to help decide on best tunes for the m157 platform.

While this thread primarily talks about his stage 1 tune, he also compares his times to a couple of stage 2 guys as well.

Amg63-

Thanks for the thread. Well, there you have it.

EC stage 2 tune ran 11.0@128mph on a pretty hot day.

AMS tune ran 10.85@129mph, and im sure that EC tune has a 10.9 in it.

I personally wouldn't be picky which one i did. Im going to look if i can see current results from weistec,renntech etc but i think its all rather close between them.

WANTED!!

No problem. Bear in mind, driver mod also plays a role in these results as well.
Don't know if this is a concern for you or not, but AMS only benchtunes and is not planning to offer a flash tune like some tuners are.

Amg63-

I wasnt aware of that. I do believe becnhtune may yield a bit better results thought. I have a local EC shop, so i guess i dont have a choice anyway here.
