I sorted out my rough start issue and it was not related to the supercharger or install
It was a bad coil. I still dont undrstand why it only gave issues /threw codes at startup. I replaced it and the car runs perfect now!

I think they are actually the same s/c unit. I have spent a lot of time communicating with ESS asking what I am sure were dumb questions 
They always got back to me within a day or so. They mainly do BMW's, but the GM has a C63 and thats what the system was developed on. Weistec is definitely the way to go if you have lots of $$ and want to go as fast as possible / lots of mods and for custom tuning. I was looking for something reasonable that I could keep my car mostly stock (no headers, etc) and still get good power. I have the MCT tranny , but the ESS tune adjusts throttles somewhat in the mid section so you get close to stage 2 Weistec power but it is supposed to be safe for the pre-facelift 7G trannys from what I understand. (they also said without that they kept spinning the tires below 80mph lol) .. Not sure how this will affect 0-60 times or the dyno....

i was hoping i'd be able to get similar performance from the ESS kit vs having to sell my legs and arms for the weistec unit

The difference is in the mapping.

The ESS system is basically the max power that is safe in a non modded or a semi modded car. To get more you can add boost, but you then also need headers, transmission mods, crankshaft pulley mods, etc - basically eveything the weistec stage 3 kit is....

Ok I know the car made 640 whp but isn't that on a hub dyno. Wouldn't the wheels on on a regular dyno rob some of that because you have friction, weight and the fact that force away from center ie torque acting against. Still crazy.
If the engine was to be built and so was the transmission. and you ran the thing on E85 and more boost, could you get away with using say PLM or VRP short headers which aren't long tube style but just log style with bigger diameter and also retain the stock catalytic converters? Maybe like 700whp?
By the way this thing needs a killer chiller.

The problem is the primary cats are far too restrictive to push that kind of power without blowing out the cat or sending EGT through the roof. The PLM headers are a nice shorty header. VRP resells the same product for 300 dollars more...
A stock bottom end non p31 can handle 700+. Perfomance Pack maybe another 30-40 on top of a non-p31. That’s more tune related.
You need a fuel system upgrade to handle full e85 and supercharger. The problem is most people don’t understand the complexity of our fuel system. You can’t remove the stock pump. It’s PWM pump and the car gets wonky since it’s all coded in the stock ecu. The best bet is to leave the stock fuel system alone. Don’t disrupt it. Add an additional pump, larger lines that feed into each other as a Y-line and run it off a Hobbs switch. That way the car only uses the stock pumps when getting around or cruising on free way, and when you hammer it, boom Hobbs switches on and you have another pump feed. This is very custom and you would need a competent shop that you trust.
Killer chiller is awesome. But on e85 and just using the car regularly on the street. Should be just fine. If your at the drag strip yeah I can see getting a KC system. Also water meth is great for cooling. 80/20 mix provides imho the best performance and cooling. You need some water in the mix. But not too much where you quench.

All dynos read different. What really matters is your before and after.

Honestly, the cat is more of a ticking time bomb with high boost application. The stock cats are extremely durable but safe power and safe EGT’s I say 6-7 lbs of boost “should” be ok. That would put you over 550whp. Plenty of power to destroy the rear tires. You can get away with a low mix of ethanol as well. Say e30 would be more than enough.

Congrats Kavik, your post and car are all great. Also thank you for sharing this, I've almost pulled the trigger multiple times but I'm really concerned with the added heat this system might/will create. How much hotter does yours run, is it mostly when throttle is applied similar to with out a blower just increases temp higher/quicker? I know having an inter cooler has got to help but this is like sticking another heat sink on top of an already hot setup.

What is the EO number?
There is nothing listed on the CARB website. The only EO listed for M156/M159 is the pre-2012 Weistec kits (D-691-2).
There are no CARB-legal supercharger kits for any M156/M159-powered vehicles built later than 2012, and the Weistec EO'd kit is specifically limited to 6psi.

EO=executive order ID. aka code/ID to reference for certified part by Air Resource Board.
supposedly costs 10-100k to certify a single part/kit. any variation will require new certification and cost.

So I got this ESS kit as well but am struggling how to go by getting the car tune. Is the HP Tuner route works? Or it is best to send the ECU to ESS?
I am adding the MBH LTH on the car so wants to get the most HP possible Does anyone have any ideas?

Hardware-supplier tune (ESS) usually = Safest tune. It should eliminate the "it's not a supercharger issue, it is a tune issue" ... or the "it's not a tune issue, it is a supercharger issue".
HPTuners is a great calibration tool - but it is just like any tool in that it relies on a good operator. There are other tools available, & the operator is more critical than the tool.
Your post will likely get more response if you give more details. (Location, mods to car, expectations, driving style, etc). Do a thorough search, then start a fresh thread if you still don't find the answer you seek.
