You really need a good scanner to monitor the fuel trim. If a 93 was an HO it should be closer to 49 psi. Either way the pcm can compensate, to a point.

The 93 is 39 psi rail. 96-01 is 49 psi.

right, which was my concern. i figure the computer would compensate and it would end up dropping output to lower than stock

I don't think it would have a negative effect running in closed loop as the PCM would be reading from the O2 sensors and getting the correct AFR. However I would be concerned about what it would do in open loop when the computer is just running off the map.

interesting. i've found that the stock computer does pretty well at compensating for mods, i just think that i could use s'more fuel. i have pretty much every bolt on you can get for this engine (oh man im so hardxcorex) save for a computer kit. i really need to build an adjustable map and get a nice AFR meter on my jeep..
