I don't know what all has been done to the car, I believe it already had some head/valve-springs work before the cam, along with some exhaust. I will ask them to post all the mods when they post their Dyno stuff.

Sounds a little better than stock, The stock LT2 with an open exhaust sounds like an idling fishing boat in shallow waters. Sounds lame. At least that cam sounds SLIGHTLY better than stock.
Stock cam has minimal overlap, high LSA and not much lift. If GM could put a larger cam in it stock and not trip the misfire monitors they would in a second. It makes ok power because of compression, displacement, head flow and direct injection. Put a real cam in an LT2 and it will scream.
When I had my LS3 with an open exhaust, I used to be embarrassed to be advertising the fishing boat stock baby cam idle. When I stepped up to a GPI NFC 4, it sounded aggressive and mean. NOT like a trawler!!

That lope sounds as though they are taking it right out to the edge. It sounds like with another couple of degrees of duration that it would stall. Curious to see the dyno graph. How much high end does it gain and how much low end does it sacrifice?

Just saw this on BD Facebook. Looks like 88rwhp gain

Lol! this is what my friends with 911s say about my car and it has no cam... haha long live the small block truck mow-der!!!

Tractor w 1200HP
I think this is the exhaust

Another Peitz Cam + Turbos example:
HP Tuners has opened up a Whole New World. Very exciting to see how quickly the tuning community is taking advantage of access to an Open ECU.

Yeah, locking down the ECU doesn't make sense unless you want to avoid massive warranty claims, and potentially billions of dollars of lawsuits when people realize they can kill someone by hacking their car remotely, or causing chaos in cities by shutting cars down on major roads.
Do you leave your home and work computers unprotected?

Cars have internet connections that can change programming, They have automatic braking systems, they have electric steering and brake boost and can automatically steer. There have been years of people tuning their cars, breaking them, and setting the tune back to stock to get them fixed under warranty.

For example: put safety related fly-by-wire type systems on a dedicated board with all the hardware lockouts and leave the performance stuff up for grabs to do tuning. I'd also bet there is a way to trigger some kind of "has this ever been tampered with" to alleviate the 'reflash and take back to dealer' issue you mentioned. With the amount of engineering that went into locking down the whole thing... I would make a $1.00 bet with the kind of mindset I mentioned above, it could be done and accomplish both their strategic/risk-management goals and also satisfy the tuning/aftermarket world.

really good points. I bet there are potentially unexplored ways to mitigate some of the legitimate existential threats without locking down the entire system.
