Renntech tune review with 82mm tbs
I decided to go back to renntech tune after trying a few files with my old handheld and man I forgot how well the renntech tuning is.
No more clunking coming to a red light with the transmission and the car shifts like I just installed a new transmission. Rev matches are perfect with the tbs and is just pure butter..
The handheld takes 1 min to program and the but dyno says i have more power in the mid range than any other tune I've had.
Car literally drives like amg sold it this way.
Bottom line....you get what you pay for!
@roadkillrob I know you didn't want to tune your 507 but they have dropped the price of there tuning !

The owner of Renntech is an ex-AMG engineer. He absolutely knows what he's doing. I do have to concur that a PROPER tune will allow for your transmission to shift crisp and on point every single time. it is very difficult to convey to anybody on MBWorld what a proper tune feels like as they have NEVER felt a proper tune.
Many variables within the mapping directly affect shifting as load values no longer match what the TCU has mapped thus causing adverse shifting conditions. Pretty much most "tunes" sold here emit this type of behavior. People here will continue spending money on tunes that really just aren't worth a grain of salt because it has a repeated name brand. Then you have the other group of people who want to cheap out and get some quick thrills but really...did the tune really do anything?
tuners relying on adaptations clearly show that they aren't doing much tuning. the computer itself is self tuning. there is no such thing as version'd tunes. it either works or does not. if there is an update, there is an update to improve not change. versioning means you were sold a beta.

What tune were you running before? I currently have EC v7 tune hitting 492 WHP and 446 WTQ with MBH lth deleted both cats and res with afe drop in filters. It feels smooth accelerating but doesn't rev match like it used to before. It does feel like a good tune but wondering how it would compare to the renntech tune. I'll post my dyno chart when I get a chance.

Dyno numbers prove nothing as smoothing, SAE, Standard, Dyno brand, Dyno model number, elevation, temperature, etc all can inflate or deflate numbers.
Dyno numbers also do not represent driveability and startability.

Just took the car out today...driving around in a parking lot was pleasantly smooth. Then taking it on the highway and keeping it in s mode (usually drive in m) the car shifted like butter. I flored it going about 40 and the car rev matched to like 6k rpms and was so perfect it makes me want to keep the car forever now.

After getting my headers on and Velos charging $630.00 for a retune I wonder if I would have been better off spending more for renntech.
I don't like the non matched shifting for low load, gives that shift where it really really feels like it's not ready for it.

Glad to finally hear more chatter about ****ty tunes. I've driven at least 10 different cars from the same well known tuner thats popular on the forums and NONE of them drive the same. They are all over the place from revving to 3000 rpm on cold start, jerky when shifting, clunky, throttle way to sensitive, slow, fast, etc... t'o a half way decent driving car. These motors are pretty consistent, there's no way they are the same persons tunes. Then sell them my tuner's work and it blows their minds how good a c63 can drive.
People have this problem with just accepting ****ty products because no one wants to admit to spending $1000+ on junk. They do this all the time with coilovers. Their car will ride like total *** regardless of how it's adjusted and still praise them. "It handles like it's on rails" , um no it's so ****ing bouncy I feel like I'm riding a horse that's jumping on a trampoline.

Is it smooth when coming to a light in M and letting the car downshifting to 1st? As in seemless? Hows the throttle modulation? No kangaroo I assume?
In your video - shift point looks like 6800rpm. Was this just for 2nd gear or does it go to 7200rpm usually?
My eurocharged tune is junk. I modified part of the tables below 50% load an it helped throttle sensitivity but its not perfect.

I had eurocharged when I bought this car. Sucked. Both v6-v7. Car felt fast sometimes. Other times not. Hard downshifting in C mode and throttle super touchy.
When I switched to renntech my car felt like OEM+ on everything. When I use M Mode my car revs passed 7200.
