Any way to tell if my car is tuned?
I just bought a used 2013 C63. It's the first one I've driven, so I don't have any driving feel to compare it do vs a known stock (or modded) one. It has the P31 package, but last night I believe I went over the stock limited 174 MPH, so now I'm wondering if it may have been tuned by the previous owner. Are there any other ways, short of going 180+, that would tell me it's been tuned?

Send in your VIN to Eurocharged to see if they've tuned it?

Throw it on a dyno and do a 5th gear pull. I think mine went 186 mph on the dyno in 5th. That will let you see how much power you are making too
|
Where the heck we're you able to get up to 174+?? Airstrip event at night? :confused:

Congrats on the purchase. Guys chime in here but I think the P31 package wasn't ECU speed limited?

Sorry for the delay guys, busy weekend. Naturally I just went to Mexico and an abandoned runway :zoom:. It doesn't take much to get up there and it's a hell of a lot more stable than most cars at speed.
A bit of an update, it turns out it IS limited, just at 180. I guess it's 174 +/-. So tune shopping I go! |
I think the best bet is to throw it onto a Dyno to find out. If it's not tuned, as least you have a baseline for when you do more mods after! :)

Not that I know a single thing about you beyond your thread here, but you sir seem to probably be the last person who "should" tune a C63! I have a funny suspicion you will find out the top speed of this vehicle while unlimited!
In any event, I wish you and everyone around you well. |

Put it in S+ or M and get up to around 40-50 in 5th. then come off throttle and hit paddle down to 4th and then 3rd. If its a crack/pop sound from exhaust on downshifts then you are possibly tuned.

I certainly don't want to paint a bad image of myself considering how new I am, and I completely see where you're coming from.. especially without knowing me or the conditions for my comments on here. The C63 is my DD and I'm not speed racer around town. I tested the performance under very controlled circumstances. The weekend car is a fully built C6 Z06 (600+rwhp, high 9s on the 1/4,) and I participate in sanctioned racing events so I'm no stranger to high horsepower or car control.
I get it, if I found an area where I knew I wasn't endangering anyone else, I'd push it! No judgement passed bud. |
