2019 E63 S
Here is a race of an Renntech intermediate tuned E63 with Rado downpipes and BMC air filters vs. a fully Weistec modified 2014 E63S with a turbo upgrade, carless downpipes, tune and trunk ice tank. To me, this race is an advertisement for Renntech and a very bad showing for Weistec.
With my incoming 2015 E63 S, I went Renntech -- Renntech full tune and Renntech sport mufflers which Renntech claims produces 716 bhp and 859 lbs-ft of torque. I'd be happy to take on this full Weistec modded car at an airport meet and see who is faster.

I was stunned at the results of that race. I thought for sure that the Weistec car would destroy yours. It seemed to be pulling stronger at the very end but who drives normally at those kind of speeds. For speeds that people can actually drive on US roads your car is faster than the fully modded Weistec car. Were you surprised at the result? Harmut makes a mean tune.
Any thoughts of getting the Renntech full tune? And what made your pick the Rado downpipes over the Renntech ones?
I went with the Renntech sport mufflers because the gains are larger than the Renntech downpipes and the cost was a little more than half. Don't think I will add either the downpipes or the $5K carbon fiber cold air intake which gains 10 bhp.

Another destruction of the turbo upgrade Weistech car by the Renntech intermediate tuned, Rado downpipe E63 -- this time in a 1/2 mile airstrip race:

So you're back with Renntech I see
When did you cave and Who do I get in touch with for an Intermediate tune? How does it feel vs your old car without lsd, Can you notice a difference in putting the power down.

Call Renntech in Lake Park, Florida and ask to speak with Mark. He does sales for them.

Apparently. I just do not get how just a tune/downpipe car destroys one with a turbo upgrade and all other mods. But there it is--twice. Certainly a big advertisement for Renntech that makes its competitor look hapless and ineffective. What was the reaction of the driver of the Weistec modded E63 to this? If I were him I would want my money back.

It certainly was a full turbo build. Look at the notes in the YouTube entries below the video. If I owned that car I would be furious

Yeah I saw the footer but still have my doubts. If it truly is a full build then there is something wrong with it. Trans slipping, fueling problem? If you look up other videos from the same tuner with their full build the cars seem much faster. But I'm just an arm rest driver so I'm probably wrong.

By contrast if you watch the many videos of a Russian guy named Vasily who constantly runs his renntech turbo upgrade 2014 E63, he essentially destroys virtually every car he meets Lamborghinis, Porsches, Ferraris BMWs you name it.

A few years ago I built a 700+ hp Corvette. My dealer told me to call before I brought in.
He told me that they honor the warranty, but just to make sure that the zone rep had been there that month. He said they make way more $$$ on warranty work than they could ever charge a customer. Bottom line if you plan on modding your car get friendly with the dealers owner or service manager.

I got confirmation that Renntech turned down the tune on the m157 (hence the rating revision from 701 to ~667 HP). Mostly it was because of misfires. Also around that time they started recommending the stock spark plugs. So the RENNtech cars won't pull nearly as much but I am convinced now that I spoke to RENNtech that I made the right decision with my tune choice.

I am going there in 2 weeks to have my car re-tuned/dyno tuned for downpipes and going to tell them to turn it up
i assumed they turned it down on the canned tunes because it was hard to convince most casual buyers, that just wanted a tune, that they needed to buy $500 renntech spark plugs too and figured they would sell more tunes if it didnt come with caveat of needed new plugs

what else did they say that made you think they were the right choice?

But considering the typical cost of RENNtech products, $500 is really not an issue for most partakers of the brand
But I certainly did ask for the hot stuff too

FWIW, I purchased my tune (RT) prior to the turned down version, or whatever it's being called. When I saw the new numbers were posted, I called to see if I had outdated software and needed an update. Was told, no, if you're having no issues, keep the tune.
Putting my car on the dyno on Monday. Currently has renntech tune and bmc filters. Will go back on the dyno later that week with catless downpipes and updated tune.

I'd be doing it on the E63S right now but latest tune requires ecu shipment which I don't want to do, so it's stock for now.

Just received my ECU back from AMS and I love the way it drives. Only thing I notice is in amg or S+ it seems to shift hard up and down around 2-3 and 3-2. Not sure why since they have been tuning it for a while. Not sure it that's normal

I think that's a common issue. I have that as well. Try it in M mode and it's even harsher.
