    in a single turbo log style you have 1 drivers side o2 in the crossover. then the 2nd bank o2 in the down pipe. If you put both o2s in the cross over both o2s only read one bank. Runs like crap after it warms up.

    Yep good good thanks for all the help guys, sorry i was freakin out. Just have to figure out what else I can do to squeeze a little more out without getting in the motor again. I was hoping it would have been around 280 so i could milk it to 300. But LQ4 will make up the difference it's just time and $$$. I'm happy with what it is though nice steady increase throughout the rpm's and solid torque will try to post charts for anyone thinking about this cam.

    Not him personally just his thought process, "Hmmm OK let's make a change to the biggest factor in an engine's operation, on a computer controlled engine. Gee I wonder why it's not running right? No the fact that the PCM is still setup as GM set it up has nothing to do with it, can't be it."

    Now yes I realize that's a baby cam and the tune won't be that far out, but it is out.
