I’ll try to make this short but I’m taking my “new to me” stock 2012 to get it detailed because it’s sat in a garage for 4 years untouched (it’s gross). Anyways, while it’s being detailed I’m going to send the ECU in to have it flashed and have the fuel tables adjusted to match the Brock’s alien head exhaust (full headers). BUT… I do not have the exhaust installed yet, it’s still sporting the stock cans. So the question is, will I be safe to drive it home from the detail shop (35 miles) with the stock exhaust but having the ECU adjusted for the new Brock’s exhaust? I’m assuming it’ll be fine… but wanted to make sure. The reason I’m not installing the Brock’s exhaust is because it won’t be here for another week, or else I would just throw it on.
