SD to mass air, back to SD?

[fiveohpatrol]

I found a good deal on a Pro-M optimizer and the conversion wiring harness over the summer, so I converted over to Mass air and didnt FEEL any loss in hp but I know there could be a little. I wasn't having any idle problems at all before (or after), just converted to have it for the future when I have a serious cam in there.

I have the wires from the MAF spliced into the computer wiring harness, as well as 2 others that go to the VSS (it died upon stops before i did that).
Would those wires cause any problems being spliced into the harness still if I put the SD processor back in there? If so, then I'll just leave it as is because I dont wanna pull all the wires back out. I was gonna try it at the track with SD and the MASS air computer's (and intake tubing) to see if theres much of a difference to worry about.

Then again, although I've heard it works well with SD, I'll be putting in a B cam in the next few weeks and I dont want it to idle bad.

Oh well, what do you guys think I should do...?

Just leave it, its not worth the trouble for the small amount of HP
or
Switch back because speed density rules!

thanks guys
