To be honest, the only reason not to try the 3.6, then go to 3.4 assuming all goes well is that I have heard that the pulley is a PITA to pull off without the proper tool. So in order to save about a $35 tool rental the second time and about $75 on a pulley that I won't use, I am trying to be smart up front. The truth is there may not be a lot of experience with my current situation. If that's the case, I will just have to try it and see, then report back my results. I was really just hopping someone could verify that my math/logic made sense or could point out where my thoughts were flawed.
FWIW, has anyone read the MAP sensor or put an absolute pressure gage on? The boost/vacuum gage is good for letting you know how things are operating, but absolute pressure seems like it would be interesting to know on occaision.
Again, I appreciate the responses.
