    timing flat lined while logging today.

    on my way to work this morning I had the data logger going. had to get on it just a bit to get over in traffic and it felt like power was WAY down. got to work and scrolled back to that spot and I noticed timing was flat lined at 27.5 for a good portion of the log. it made boost and put fuel to it like its suppose to. but it was flat lined before I gave it throttle and well after. I can't load the log until I get home, but can somebody give me an idea of what I could look at. I would think it was a data logger fail if it wasn't for the large lack in power. I just want to make sure all is well before I drive home.

    ok looked back through the log. looks as though the logger did go wonky. the tables in the boost range actually didn't show any numbers at all. so that leaves me to wonder why power felt off. my only guess is the trans didn't downshift. just did an 80E swap the other day, my guess is the down shift perimeters are off. I was doing about 30mph when I stuffed the pedal. I'll look at those on my next smoke break.
