Default 2 codes: P0106 & P0121

I'm getting 2 stored codes - P0106 for Map sensor and P0121 for throttle position sensor. The P0121 also shows as a pending code. The engine seemingly runs fine at all times though...as far as it feels at least.

Are the two related in any way?

My scanner shows TPS to be 0% at idle and 100% at full throttle so doesn't seem faulty? The map sensor gives a steady reading at idle too..

Feel free to chime in!

You need to raise the P0106 Error Map Calculated Max table to be slightly higher than your actual Map Kpa. This is due to the higher, low RPM Map Kpa when a performance cam is installed.

And the P0121 Error Max table should be set to 100 KPA, and the Min table set to 0 KPA. This will fix the P0121 code due to the higher, low RPM Map KPA with your cam.
