the thing to remeber when a mod like descreening the maf is done is to compensate for the new air flow and the change in the counts that the sensor will see.
if the screen is removed and the tables are not changed it is very likely that a loss of power or odd spikes in power will occur.
that is the advantage that craig has with a program like hptuners. he went to their web site and did a quick search and found the correct adjustments to make to compensate.
tuning is always the correct last step whenever changes in airflow in or out of the engine are made. in a perfect world everyoen would have access to this stuff.
