I am installing my NISMO LT headers next weekend and was wondering how lean I would run without an immediate tune adjustment. I will have to drive at least 20 minutes from the shop to my house post install because I don't want to run the risk of crashing the ECU unless my truck is at the house. Thanks in advance.

While it may run lean and therefore a tune may be in order, Nissan approved headers are not going to flow your ECU...CARB wouldn't approve with that stipulation.

i wouldnt worry about it at all, you will not lean out any where close to causing any damage at all...
