Red face How to flash ecm with efi live?

I'm not the best with efi live but I just bought an autocal with preloaded tunes and dsp5 switch. I installed a lbz mouthpiece and s&b cold air intake and it won't go over 2100 rpm's. The kit said I needed to re-scale the mass air flow sensor by flashing the ecm. Is this something I could do with my autocal or not? If so, how? Thanks!

Make sure you installed the MAF sensor... If you need your tune modified for the intake then you will need to contact the tuner that wrote the tunes on your autocal to update them!

I custom tune all kinds of stuff and try to make them go faster, breath better, and play nice.
When in doubt, 0xFFF it out

A few rigs in the trough... Couple fords, duramaxes, and a little ecodiesel with a lot of heart!

Thanks a bunch! They already factored the lbz mass air tables into the tunes so to hell with paying the dealership $100 to do it.
