Dtc p0103 I have a 69 Camaro with an LS1 conversion. I used a stand alone wire harness and computer from CMB Motorsports.
Right after they turned and dyno the car I developed this DTC code mass air flow circuit high.
I cleaned the brand new sensor. No change
I replaced the brand new sensor. No change
The harness is brand new. Cant find any frayed wires and connections look good.
There are no leaks and everything is snug on the cold air filter system.
With that said, what do you think the problem is. Could it be the computer? I am taking the car back to CBM Motorsports but I am reaching out to some of the experts on the board for their opinion and input.
Thanks

They could have tuned it in Speed Density mode. If so you have to purposely fail the MAF in the calibration to force the vehicle to run in SD and that code will always be there.
I am going to agree with 2xLS1 and what one of our techs told you. But bring it by and we will check it out!
I am guessing that the check engine light is not on but if you plug in to it, then it shows the code?

Thank you CMB Motorsports!!! Met with the owner Chris and he educated me on Speed Density tuning on motors with a non stock cam, etc. He tuned my car and she is running great.
You guys are awesome!!
