Default Question on codes from first time at the track

Finally got to go do a couple of runs for the first time since mods. Times sucked but just driver mod issues. Lol. After the second run I got a SEL and read the codes today. Looks like both 02 sensor bank heaters and a map sensor code. P0036, P0056, P0105, P 0155. Any idea what would cause them to all go at once? Mods are Heads fixed, milled 20, cam tsp LS7S, killer cold air, long tubes and x pipe.

I can possibly see the O2 sensors failing. It may be a little rich or something else may be off. Not sure why the map sensor shows as well. I’m not real versed on what all will trigger other codes at the same time. If they are related.

I was going to ask as well. O2 sensor heater issues is a fairly common problem with TSP headers.

Not sure on the MAP sensor code. Check the connector and sensor for any obvious signs of damage or missing bolt.
