Get the code checked, it could be running on the low octane table or have other issues. Don't worry about the trans until you fix known issues first.

I am going to check the code today.. I am also going to change out intakes to a 85MM intake and throttle body this weekend.

I will then recheck the plugs and wires and cylinder pressure also this weekend.

I would think you would have mentioned the SES in your first post...

That could be the whole problem. I wouldn't have run my car without knowing what the code was first.

I had the code checked today. It was P0300 random miss fire. I did a search and that seems pretty common with aftermarket cams.

It went off about 30 minutes after I left having the code checked.

It still set for some reason, its not like you fixed anything.

Converter looks a little small, and I bet your shift points are not really 6200... I recall ten years ago my car running like that and it was shifting at 5600. I manually shifted the car to an 11.7@114 from a awfull 12.8@106 start.

Street and dragstrip are 2 totally different things.

That P0300, could be a sign of a problem, maybe not. I'd pull the plugs, make sure nothing funny is going on there, swap the wires from 1 side to the other for the hell of it, same with the O2 sensors, see what that gets you.

Something is absolutely not right, what, I don't know without seeing the car run

I will try this too this weekend.

I am thinking about getting a raptor shift light and shifting it manually at the track. Maybe that will cure some of the problems

I always had better luck manually shifting my old 00 Formula.

I would start by trying to find the miss fire issue. Could be a bad coil pack, plugs, plug wires etc. Check for arching in the dark.

Usually people upgrade intakes before getting the tune - I assumed he was running at least the ls6 with the size of the cam and close lsa. It's a big cam for stock cubes, doing a search it looks like 6,400-6,500 is where pk HP happens for most.

If you had a misfire code AFTER the car was tuned, then that is a huge step in troubleshooting your issue.

Yep, new intake,throttle body, and fuel rails are going in this weekend. My plan is to pull and replace all the plugs again this weekend. Replace all the plug wires with 8.5MM wires.

Then I am going to schedule tuning with a different tuner and see what happens.

PO300 is from doing the cam, I don't think it's going to rob power.

If your rev limiter is at say 6400, you can then manually shift the car a few times and see if the times improve.
