Maf readings
Just curious on what kind of numbers I should be looking for. Did a 2500 to 6500 pull. Hci 99 FRC. Starts at 47 g/s and goes up to 223 g/. Very linear curve. Are those normal numbers? Thanks

Tunable MAF readings are best addressed by the MAF "HZ" table
Both HP and EFILIVE use the HZ table to alter fueling and data logging
A stock C5 may top out at like 8500HZ The more modded your car is hds/cam /boost- ETC- the higher the recorded MAF readings will be --They can go as high as 11000 HZ-----
A 1999 C5 MAF HZ table maxes out at 12000 HZ so if your HP level produces enough airflow to exceed 12000 HZ your fueling becomes static after that and you risk leaning your engine down and damage
Data logging your MAF readings using the HZ table is the only way to be 100% sure you have enough table left-----IF you do exceed 12000 HZ there are other tuning options that come into play---Like an open loop tune or a speed density tune---
