Well, here we go, another newbe making the same old mistakes! But, I was hoping those more experienced can offer some help. I just added a tuned pcm and am having a host of problems. I have a wizair intake installed, but was interupted by some family issues and have to wait a few days to get the 3.4 pulley on, and the colder plugs installed. I know I need cat-back work (stuff on order), but the car is bogging out horribly. Will I see any damage running with just the pcm for a few days? It stutters on anything other than the lightest amount of gas, and I am not brave (or stupid) enough to even try WOT.
