A friend of mine had his front lip damaged on the freeway the other day. if he gets a new one i'm going to try and mount the lip on my car. Will report back how it works out.
People think the non-CF spats are permanently attached. They're not. And if you look under the non-CF bumper you can see all the hole locations for a full lip. I would be shocked if it didn't bolt up.
It's for the downpipes. I'm going to let the ecu see the code for a while and see if it learns and shuts it off. Nissan ECU's will throw codes with straight up cat deletes and then after a few hundred miles shut off when they readjust. with the mini cats on the BW it might do the same thing.
Well my CEL did come on when I went back onto the dyno. So here's the thing: the stock ecu looks for a tq target, and once it hits that tq target value, it starts pulling back boost pressure. I learned this after talking to Christopher Berube, GM performance division lead program engineering...

I can't say my experience isn't anecdotal, but these seem about the best versions of this type of product.
Once I dyno again I'll tell you how the factory software is dealing with it. The blackwing computer has a tq target and after it meets it, it starts dialing back the boost pressure. So I think what's going to happen is a wider and flatter torque curve with earlier hp but similar peaks.
