Still plagued with this light its always p0300 can erase it and it comes back after start up but if clear it then drive stays off. I guess i have to start with pulling the coils ? Then onto fuel injectors? Should i just take back to shop can they get more detailed info on the code being pulled to help zero in instead of just guessing like i have to do.

I'm not noticing anything with these codes maybe on start up idling high then settles. I know he said should look at replacing o2 sensors were acting erratic but shouldnt be a issue he said. I can't feel the car driving any worst. Obviously feels better with the sc.
You ever figure anything out about the misfire? I got a vortech setup and I have a random misfire that I feel but no codes. I have all new coils and spark plugs, trying to figure out what's next.

Took back in to RT tuning and they turned the random misfire code off. Most of the time with osiris they said they turn it off but every ecu is different. At first mine wasnt reading any codes then started pulling this code. That code is very common with FI they said. Havent had a issue since they turned code off. Now if actually get a misfire code i will be able to tell which cylinder its coming from.
don't know if this would happen at this level of boost, but have you considered that your p0300 could be caused by spark blowout? you may try closing the gap on your plugs a tad... maybe to like 0.040 instead of 0.043 (stock). or increase dwell time if you get a better ignition
