This has become way more interesting than I ever thought it would be. I love learning this stuff. I somewhat mis-spoke though. I get typing faster than I can think.
My immediate reason to upgrade ECU's (to FAST, maybe now) is to be able to retard the timing under boost. Mine's not even doing that now. That's #1 priority. Altitude stuff is just another part of it. I don't really travel from hi to low or vice versa, but it would be nice to not have to screw with it. I will continue my research and check out Lance's. Jody, you know anything about these? Maybe I just need a boosted LS7
