2 bar MAF with custom O/S??

[thunder550]

Is this possible? I have the 2-bar custom o/s installed but I want to try to fix my lean on throttle tip-in issue, and I heard that re-enabling the MAF would allow the PCM to respond to throttle changes faster.

Don't re-enable the MAF! You should be able to fix your lean tip in problem without the MAF. I've done several 5.3 Whipple tunes using the 2 Bar O/S with no problems.
