I forget, does your '92 have speed density or mass air flow for the air intake flow on the EFI system? If it is mass air, I was told by my SCT dealer that the EEC-IV EFI systems (with mass air) are very forgiving about adding engine mods with out the need for a programmer to accomodate the mods to the engine. So you can change the cam, heads, intake, etc... and the EEC-IV should be able to handle it ok. Even with speed density, you can bump the timing without worrying too much about causing computer issues, as you already mentioned doing.
see about that though i havent got the truck yet. i should have it by next week. but im starting to get worried because he decided to put it up on craigslist yesterday. but i can understand its taken me a week and a half to get someone to buy my truck so i can buy his. im worried though cuz the truck is in such good shape for the price it might be gone. im thinking i might be able to give him 100 dollars to show him i will pay him the rest when my truck is sold.
MAF works a lot better with mods than speed/density. However he should have speed density. I don't expect ford to start using the MAF system on N/A motors until late 94 and 95.
