how to reset PCM? dark soon help!

How do I reset my PCM? Where is the Fuse?

What should my PSi be at with my mods?

Will this reset stuff pcmforless did or the dyno tune I got?

Unhook the negative on the battery and wait 10 minutes. The PCM will re set and clear.

On a 1995, find the PCM BAT fuse in the underhood fuse/relay panel. Pull it for at least 30 seconds and you should be good to go. Removing power from the computer will not erase any programming.

WOW, 95's are way different than the 97's, on my car that fuse is in the fuse panel on the side of my dash.

That's right. Actually, 1995 is the only year that fuse is under the hood.
