I am getting mass air flow codes p0102 I believe anyway maf low voltage code

second code is evap emmission control purge valve then this unknown fault np or nd 0026

after a 10 minute run the truck refuses to start unless it sits for 30 minutes even after clearing the codes

or last night i reinstalled the tune and it fired right up

Tired of high performance engines. please help

Is it a stock MAF?
Check for leaks around the MAF or blower inlet.

Thanks
