That’s interesting. The PCM is my roadblock to forced induction. I don’t want to invest in it and not be able to use it.Not being able to reprogram for mods such as a supercharger or turbocharger is (perhaps) NOT exactly true. Look at the very first comment, the one all the way at the bottom, on this video below.
Rob Sullivan says (and I quote): "I had my pcm from Wranglerfix in 2 days. I installed it, then my Sprintex tune without any issues. It’s been a few weeks of driving and have no problems at all"
I asked how he did this and he has not yet replied. And there is no way to know if Rob Sullivan is being honest, And you are 100% correct ...Mark does claim his PCM cannot be tuned with a programmer
FI costs would go a long way towards an LS swap but I prefer to not have to swap.
