Default Time to tune and boost my 98. What MAP? Still using MAF

Time to start breaking stuff on my close-to-two-year build up.

Anyways...
98 PCM and wiring harness
I have EFIlive Flashscan and Roadrunner PCM to replace my stock PCM.
I am still using the MAF.

Do I buy the usual GM 2bar sensor for my setup? I won't be running more than 15psi for at least a year or two, only 7-9psi for now. Sorry if this is redundant, I just know that the 98's can be a pain.

Anyone??

Being you are going to use the RR I would get a GM 2 BAR MAP and run it in SD. With the RR making changes with the real time tunning options make SD tunning a breeze.

Just a thought.

Doesn't SD in an application like mine require tuning adjustments as the weather changes? If it's at all possible, I'd like to keep the MAF but if it's necessary I'll go SD.

If I pop a 2bar sensor in, I need to "half" the kpa table to adjust the kpa in boost right?

I honestly did try the search and was up all last night browsing. This board is a fantastic place but some features just never work right. I need all the SD vs MAF info as well as some other features like MAFTpro and such.
