I literally just got off the phone with someone over at JWT. I started an order to retune an ECU a couple weeks ago and forgot to add on ls2 truck coilpacks. Called back and said I wanted that in the tune.
I was just informed that they do NOT need to modify anything in order for me to switch from stock to LS2 coilpacks. "Do whatever you want with the ignition as long as it is being controlled by the ECU."
THAT IS FUCKING NEWS TO ME! I'm calling BS, but can someone please shed some light on this?

Every thread I've read that was credible regarding the swap stated that a retune was necessary. I'm about to be REALLY f***ing pissed if I just spent all this money and the ecu isn't worth poop for my setup
