My bet is you just discovered your problem. Sounds like a problem with the tune. You're in NJ so I'd go to ECS and have them fix the seal and the tune.

I just recently installed a d1 tuner kit with a 4.75 pulley on my c7, car is bone stock besides procharger kit, double and triple checked my installed to make sure everything was installed properly, I live in southern New Jersey and brought it to a highly reputable performance shop in the area to have it dyno tuned, they put it on the dyno and the front main blew out, they blamed it on a combination of too much boost (9-10psi) and prochargers pcv system, had them fix the front seal as well as integrate there pcv system that they claimed breathed better, also had procharger send me a 5 inch pulley to lower the boost and the shop had to machine the pulley to clear the throttle body, while intergrating there pcv system they said that prochargers check valve failed therefore causing the seal to blow, so they put it back on the dyno to find out that the rear main seal blew out now, they contacted procharger and they simple said oh well, we'll send you another check valve but won't cover any damage done, kit is brand new, there are hundreds of these kits out there on c7s without issue, now I am in thousands of dollars worth of repairs and the car hasn't even left the shop, beware of procharger, honestly debating about taking the damn thing off and selling it, procharger should stand by there product, such a disgrace and will never buy or recommend any of there products.
Procharger adds on to the stock cast pulley. A&A uses a new balancer
and new seal.
Lots of both kits out there with no issues. Sounds like not sure but install issues.
I don't think Procharger make's check valves.

Most are running a much more open system like the LMR or FSP cans that allow much more venting of the crankcase.
I blew my crankseal naturally aspirated with 416ci 12:1 compression and high teens spark lead and the stock PCV.
I swapped to a LSx seal, 12psi boost, 10-14 spark lead, and an LMR breather system and no more leaks.
Bottom line is it really depends on what was still stock and what was changed. IMO, a lot of FI kits are not complete regarding PCV system. When you want to build a better football team, nobody ever considers upgrading the water boy.

Weird. It's almost like you've already created this thread. Oh wait, you did. I don't know why you felt the need to restart this.

Unlucky really as there are probably over 100 procharged C7s and you're one of the few with an instant seal blow. Could have been a defective seal from gm, defective check valve (I highly doubt procharger makes these themselves), or else.

Has this particular shop tuned a lot of C7's? They can be tough... If they are too rich it will blow the seals out along with a few others reasons. We just did a blower and headers on a C7 with 8-9 psi and its been great. Along with a bunch of others we have done.

too much spark was indeed creating enough cylinder pressure/blowby/crankcase pressure in early builds that would cause the crank seal to leak however, it can also be caused by the pcv system as it is not really up to the FI task, IMO.

The check valve we use in this system is the same OEM part we use on 90% of our other systems. That means literally thousands of them have left the doors of this building. This is the highest quality part you can get to do the job, since its been tested to endure the abuse that daily drivers get. Ultra cold temps, ultra hot temps, chemicals, etc.
They are a very simplistic design, so that lends to their quality level. I have yet to personally see one not work. (I check each one that I install before putting on for good measure) And I also trust my daily drivers 207,000+ mile front and rear main seals to one of these check valves, since I run the same part on my own vehicle every day with boost.
Yes, other companies make full blown breather systems. HOWEVER, as nice as they are they are not 100% needed. As proven by our countless customers, as well as other supercharger systems that do not run them.
If we felt we needed to make a catch can for this sytem to work perfect, we would manufacture them, and include them in the systems. However with all of the testing that we did (and are to this day still doing), it was not found to be a "needed" item outside of full blown racing applications. So thus we can leave that up to companies like LMR and others to enjoy the profits of making that aftermarket PCV item.
