Stroked 1992 XJ Questions

I have a '92 XJ that I will be stroking soon and was wondering what computer/sensor modifications I need to do. Unichip does not produce a piggyback for pre-93 and I have not found any good information here or on Pirate. Thanks for your help...

24# ford injectors is all you will NEED. Chances are the stock ECU will do a good job handling the AFR, i know mine does.

I have one on my 91. It's not exactly PNP; has to be hardwired into the ECU harness and will work on all OBD1s. Easy to do.

Same here. Ford Racing 24lb injectors, stock computer, stock MAP voltage, and stock fuel pressure regulator. Goes like a raped ape.

I think it depends more on how nuts you wanna get on tuning.... mine could run a scosh richer and WOT (and i plan to use my PSC to impliment this when the weather warms) There also seems to be a real HP wall around 4500 RPM, my friend felt it too, he asked if i let off the throttle cause thats how much it dips in power. I have yet to make a recording with my AFR setup to see what happens to the exhaust gas when that condition occurs
