welll its stupid to post a thread like this and then not say what happened…
the is300 tries to hit a target afr of 12.5 on its MAF based system… which is why you can bolt up a supercharger with NO aftermarket fueling computers or injectors and still be fine up to i think i remember 5-6psi…
but whatever :tdown: for not posting the story and posting a thready like this… you invited the hating on yourself
