Re: DTC P0300 (engine misfire detected) Yes it could be cam. Once the car stumbles, trying to find an idle, it can set that code. Did you drill the TB? I used an 11/64ths drill bit for mine. That and the predator, and now she idles good. Glad you got it back. Enjoy.

Re: DTC P0300 (engine misfire detected) Don't know about the predator. LS1Edit will fix the SES and hard start. Edit is more involved than using a hypertech or predator, but Edit is more powerful.
You could also find a good shop and have them tune it.

Re: DTC P0300 (engine misfire detected) Yep, Predator can turn the SES off, and clear SES' anytime they are set. The Predator is a very ppowerful tool as well, just have to rely on someone else to write the tunes. Much like if you have your car tuned at a shop, they write your tune, not you. And when you mod more, you can adjust again. Depends on your preference.

Re: DTC P0300 (engine misfire detected) I get that all the time, you need to do some tweaking to the misfire tables and you'll be fine. It's common with larger cams.
