What about them jet performance chips??BoostedNW might get them back in stock at some point. You need this: G1 adapter. OBD1 stuff is getting harder to find since Moates went out of business. Alternatively you can solder a 27FS512 chip in place of the original ROM inside your memcal but that is not especially easy unless you are good at soldering. 27FS512s are getting very scarce nowadays since they've been out of production for years so if you have no intention of burning the chip multiple times you can use a EPROM. Then you can burn the chip on a chip burner like my XGecu T48 and a memcal adapter to burn the chip. Finding an original memcal from a 94 or 95 truck from the junkyard might be easier!

Well when I purchased the truck she was shutting off randomly and having bad performance and I took her to the mechanic and he replaced EGR SPARK PLUGS ECT but when the inside of the truck gets hot she runs like ****. Mechanic suggested it was the pcm
Did someone do the diagnostics to determine it was indeed the PCM? If not you have a long way to go before you get to the ECM.Also she surges and sputters replaced fuel filter as well
