A) You don't need mass air for the mods you have planned.
B) I think you'll have a better performing motor with better drivability using the stock 460 computer than you would with an SEFI 5.0 computer unless you spend the extra $$ and get it tuned.
If you were doing enough to the 460 to require bigger injectors(heads and a cam) then I would strongly suggest you do a mass air conversion and get a tuner. But for your relatively mild buildup you'd have to invest quite a bit of $$ and time in tuning just to get it run as good as the stock batch fire system.

Well now my question is what is exactly the threshold that the SD system can handle? I'm planning a fairly mild build for a 460 which basically consists of porting the heads and intake (if possible and if necessary. Though I hear the breathing flaws rest more on the exhaust side) and an RV cam (along with headers, dual exhaust etc). I'm not aiming for a speed demon. not aiming for something that needs a radical cam profile or over sized injectors Just something with a bit more grunt than stock. Can a SD system handle those kinds of mods?

Can I modify and use the T50 kit? The PCM is for a production '93 mustang with a strategy of A3M1. Only the function of pin 30 (NDS) is different between the two systems.
I could return it and get my $500 back.
I hope I did not hijack this thread.
Thank you,

I''ve got the same situation and I've spent hours reading all the MAF conversion posts and couldn't find the answer to this question. Can the M9000-T50 Ford Racing MAF Conversion Kit for 87-93 F150 5.0L Trucks with a manual trans be used on a truck with a AOD trans? If not, what change(s) need to be made? If the ECM is the only difference what ECM can I use with the rest of the Ford Racing Kit. Any hel;p would be appreciated>

Auto computer on a manual?
I am preparing to do a MAF conversion on my 91 5.0 manual truck. I was able to get a good deal on a MAF computer from a 95 truck with 4R70W. Will I be able to use this on my truck? Or will it throw a code when it doesn't see the transmission?
A couple of months ago lmd91343 among others were talking about using some of these 4R70W computers, but I am not sure if they were just talking about using them with an E4od .
Thanks...

At least with the stock code/data.
