I checked on Tire Rack and the website says r888r's are not available in my rear tire size. Does a slightly different size fit?

Saudio

When I was talking to them on the phone they quoted me these numbers at first, then corrected themselves. They say they are working on the website. But I agree it's silly to not fix that stuff right away.

They advertise as having sold 50,000 tunes. At $1500 a tune, that's $75M. Maybe a couple hundred spent on the website would be wise ;-)

Interesting, I was only able to find that link via a google search, if you go through their website you can't bring up that page.

Thank you!

sent that link to my wife. *christmas gift*hint*hint*

ya you don't wanna do that if you are tuned... the tune did that already for ya with software

google is horrid with bad cache removal but damn fast with picking things up same day lol

Orcbolg

Agreed. Figured that was the case, so I sent support a heads up about it as well after he posted it.

Just one thing to consider: If your rear wheel rims are the GTC 20", they are 12" wide. The 315/30/20 R888r can fit to a max of 11.5" wide. You may want to consider the 325/30/20 for the 20/12 wheels. Their section width is 13" so there is enough room in the rear (I'm using Michelin Alpin PA4 for the winter with section width of 13.5" with no issues whatsoever). Their diameter is 1.8% bigger (nt an issue), so you will go 1.8% faster then what your speedometer shows.

I have a pedal box on my c63, couldn’t be happier. Speeds up the throttle response.

I have a GTC with a RENNtech tune - it doesn't get rid of turbo lag. So, my choice was downpipes (I already have removed the secondaries) or try pedalbox to see if it can be tuned to hide the lag. It's much cheaper and less invasive than downpipes. It solves the problem! The nice part is its highly adjustable to get the response tuned to your liking, and with the bluetooth option you can tuck it away and use your phone to fine tune it.

Like the EVM, its a low cost way to tweak the car for maximum results.

For a tune call Steve Dinan, at Carbahn. He has a tune that has a warranty behind it. I used DME and eurocharged in the past to great results, but Steve’s goes a bit above and beyond.

Same here. Love it...

What exactly is the purpose of the pedal box? If I'm understanding it properly, it just tightens up throttle response from the go pedal?

Skilly

Correct - With it, the vehicle reacts much faster to incoming signals from the accelerator pedal. It's a little more specific than a simple range amplification though. It is tuned vehicle specific so the throttle mapping becomes more integrated than just a hyper responsive throttle response.

Think about it like when you drive the car in a 'spirited' way and it learns and adapts responses to give you 'more' because it learns your driving style. It's that, but adjustable and at the ready no matter what you have been driving like for the last several runs.

ZephyrAMG

That's a great explanation. I don't have a tune however, I am sure it is signal amplification in a way though. The unit is plugged into your peddal underneath (you unlplug your peddal and plug in the module), and when you press the accelerator, it speeds up the response significantly. It can or does not have to be paired to a tune. It's not as significant of a tune but its more of a "wow" factor. It also has "intensity levels".

Orcbolg

Interesting, thanks for the explanation. Sounds like what the Eurocharged tune does to the pedal response to a fair degree.

So instead of getting the response out of an inch of travel of your pedal you get it out of 1/2 inch of travel. Sounds gimmicky to me.

Skilly

it's not just that, or I would agree to you. Its vehicle specific and user adjustable. So it amplifies, yes, but it does it over a range rather than a simple linear translation. So it fits the vehicle dynamics rather than just making your pedal twitchy. If its a gimmick, it's one that actually works - sign me up!

I'm not even going to try to explain it. I've seen heated arguments about the PedalBox on so many different car forums now. I just know that if you're a super impatient driver (like I am), it is a FANTASTIC mod. I think I've had it on my past 5 cars.

Anyone with a stock car. (I've tried this on an Audi, Porsche, BMW, and my AMG and Alfa). Sitting at a red light in normal/comfort mode. Light turns green. Mash the throttle as quickly and as hard as you can. It still seems to take 1-1.5 seconds for the car to move forward. I have no idea why OEMs build in that delay. Drives me nuts. (If it was simply amplifying, there shouldnt be a delay if you went WOT right? I dunno)

A tune also alleviates the issue for the most part. You dont really need one after a tune unless you want a super sensitive throttle.

AMG 17GT

My 2019 Porsche Panamera turbo was the worst at this hesitation. Even pedal box never solved problem as car was so detuned from factory.

Skilly

If it’s like the 911 the intakes are choking it! They are overly restrictive so the engine is always starving for air.

UCIMBZ

Got it!
