Some people prefer to run Speed Density (SD) versus using a MAF. You would need to remove the MAF if you are at it's maximum function/limit. How much boost are you running? Unfortunately, the 98 PCM's can not be upgraded to more current OS's. I believe with HPT, you can apply a 2-bar custom OS to your 98 OS. This would allow you to properly dial in your VE table, run SD, and ditch your MAF.
Don't confuse SD with Open Loop (OL). Speed Density is a strategy to calculate airflow (or engine load). Open Loop is function of whether or not the PCM is receiving feedback from the O2 sensors. You can operate the engine in SD mode under Open Loop or Closed Loop.
You might want to read this for HPTuners Custom OS's. Here is a longer description of operating modes and feedback methods.

...13 PSI... I guess the stock MAF is maxxed out...
You'll better go with a newer PCM, 2 bar MAP and a program capable to handle it.
You'll need some rewiring too (the pin's are different)
