Tuning a C43
I haven't heard of a Eurocharged motor blowing, but they also offer a warranty
Found the link.

Edit for clarity: I definitely wasn't disrespecting the owner of the AMR tuned car. They're running some fast times and pioneering combos to seriously low times. That sort of thing can only be good for the community.

Also, to the poster above who "begs to differ", your situation is different because you're mixing E85 already. With just 91 or 93 octane, a stage 1 Eurocharged tune is just kind of noticeable over stock. It's weird to me that some people claim crazy performance, even a stock Audi RS3 claims pretty crazy numbers from the factory, but it pretty much can only attain those figures with 98 octane. If you're putting different fuel or different grades into your vehicle, then this already changes the game; it's not the tune as much as it is the fuel. Now, whoever can get the best numbers on 91 octane, that's the tuner I'm interested in.

Yes, I understand a lot of ecu tuning is re-mapping throttle response; that is not what I'm talking about. Power increase at WOT post tune was marked. My analysis is purely butt dyno....absolutely no numbers to back up my claim, but if someone told me their stage 1 tune didn't do much, I'd be raising my eyebrows. Then, I'd be telling them to find another tuner.
I always run 93 octane Shell or BP and I'm in the northeast if that helps anyone.

It’s also obvious that there is not enough ignition timing to get good power, it is very hot and humid where I live, and this is one of the reasons why the C43 isn’t really cut out for big power increases from tuning.

I also ran an unblocked CPC, which did not make a difference either.
I figured there was not much more I could do to tune the C43 any further unless major hardware changes were made, or run WMI.
Long story short, the tuning potential of the C43 is severely limited. The funny thing is when driving the C43 I constantly wanted more power, but on my current ride I find it powerful enough to not want to mod anything as it is plenty quick out of the box.
