looks like its having a really hard time controlling the wastegate up top.

Its a common problem with the vacuum wastegate actuator on the R56. Vlad had the same issue with the JCW turbo up top. Take a look at DNA, JZW, RMW and Manic dynos and you'll see it quite a bit. The fluctuations occur too quickly to show up on a datalog but it''s always there.
That's one reason we decided to add a boost port tap on the compressor housing. The next round of tuning is set to use an electronic boost controller. In our case well be using a Cortex EBC in conjunction with a Turbosmart wastegate. The nice thing about the Cortex is you can set independent boost levels for all six gears. Plus it stores six profiles. Takes a little longer to set up with a laptop but gives you much better control.

Here is the poster child picture for a Manic tune.

^ That's more like it. I was beginning to get worried about you Dave. I was starting to think you weren't feeling well or were on some kind of medication. But to the point there's nothing wrong with having a favorite tuner especially if your happy with the product and service you've received. I've installed Manic tunes on somewhere around 50 to 60 Mini's and have yet to have a client suffer an engine failure. Tuners however, whoever your favorite is are not magicians. If you lose an injector on a hard pull you can write off that piston. No magic fairy dust will save the engine. By the same token no tune will make a fuel line or water pump fail. Don't laugh at that last one as I subscribe to a great many tuning forums for a wide range of platforms and you'd be amazed at the drivel that gets out there.
So back to my point above about fluctuations on the Prince engine I've attached dyno's from DNA, JZW, Manic, PAW, RMW and even stock tunes for comparison. Generally an Eddy Current style dyno will minimize the fluctuations but it still shows up.

There are a lot of tuning options out there. Some are pretty damn good and some not so good. What I don't see is any other tuner out there besides Manic that's offering three different performance modes while being able to switch back to stock at the flick of switch. Nor do I see anyone else offering the ability to alter their tune on the fly to take advantage of methanol injection or 100 octane racing fuel. That level of capability for the R56 is currently limited to aftermarket ECU solutions like the Motec M142 or M182. -

I moved all the pictures in this thread to a non-HTTPS image server. Hopefully, that fixes the issue.

I've had my 2013 N18 Manic tuned (what at the time was called Stage 2+) since Oct/Nov of 2014 with no issues. I do run meth injection on a map that does not require it.

@Tigger2011 @oldbrokenwind - or anyone else running a Manic tune. What water/meth mix are you running? I’ve been looking around and there is the Snow Perfomance mix at 50/50. https://www.summitracing.com/parts/sno-40008/reviews/?page=3
I can also get VP M1: https://vpracingfuels.com/product/m1/
While doing some research, it appears people change this up quite a bit. Some folks say not to go below 80% meth, others are closer to 50/50. The mix ultimately adjust the intake and exhaust temps. Note, I’m new to the significantly modified turbo world, so doing as much research as I can. That said, I do need to order some before I run out. -
@Sully, I'm also interested in a meth setup. If/when you get yours, I'll come up and give you a hand with the install if you don't mind.

@Qik - love to have you up. Mine already has the HFS-3 Aquamist setup installed. That said, I’m doing a lot of research on it and want to check a few things. Also depending on which gauges I get, will need at least install those. Welcome to join there.
I also plan on doing a full service so I know where all the fluids are at etc.. my Bentley should be here in next day to two.. -

Yes the safety is built into the system. Check out the manuals you can download and read even before you buy.

VP M-1 is the only thing I have ever put in my system. Snow 50/50 Red color dye, windshield washer fluid and all the other colored pre-mixed all contain stuff that gums up the valves and the FAV (fast acting valve).
Meth is clear and VP-M1 is the best .-

So, I’ve been doing a lot of read on the mix.

Since map "C" wants 100% meth, I'm not gonna drain the only WMI tank I have, and I'm also not gonna buy a second WMI tank. So I use the same 80 - 20 mix but add a bunch of 100 octane to my usual 91 (max readily available) when I run map "C", then drive around for several miles to mix it up in the tank. Gotta do lotsa plan-ahead to do all this, but fortunately (brag brag) I seldom need map "C". An alternative would be to run 100% meth all the time. Others do it and I'm considering it, but for now I'll keep it as described above.
If you find a way to mix it by weight, a way that makes sense and doesn't require a lab or science degree, let us know.-
