l have a question as to how one would tune, flash, a t4mo to run a 351w. Possibly a 357 mild daily driver,afr185s, etc, or would a pcm out of a donor truck bolt on and adapt to mild mods?Looking for about 375 hp at the flywheel.
Not a lot different than a similar modded 302. You have to make a couple of changes in the tune for the increased engine displacement, and the normal tuning mods, and you'll be fine. We've done a ton of chips for 351 swap cars - including our own 357 turbo shop car.
You cannot flash T4M0 processors, chips/TwEECers/EEC Tuners are the only route.
Make sure you have adequate MAF and injectors for that HP - minimum 30# injecotrs, though I'd go with 42's and probably a 90mm Lightning MAF - you would need a tune for that MAF injector combo.
Yes, but using the stock MAF and injectors, I would not take it over 1/2 throttle or the MAF will peg and you'll run out of injecotr. Any MAF or injector swap will require a tune.

Should be as long as the MAF calibration is OK - sometimes they are not. I still would not get on it, because the load calculations will be off with the larger dislacement - so timing at WOT will be off.
