Tryin speed density

I have read about all the speed density problems at idle/cruise
but was still wondering what it would take to try it on my 95 TA.
I have tuner cat so i am able to make corections to the PCM. What do i have to do to make it all work.

The only thing you need to do is enable 'speed density' in the ECM switch tables, like the third one down I believe. Now for tuning in speed density, that's where I'm not sure, since I don't run speed density. I beleive the adjustments to the VE tables effects this. I have unplugged my MAF in the past which put's you to speed density and did notice my car seem to be smoother and idle better. Let me know how it turns out.
