Tuning for injectors

Huh? I'll be the first to tell anyone that nobody's tunes are perfect and that nobody can overcome physical hardware limitations regardless of what is promised by a tuning company.

I'm too damn honest to be a salesperson. That's why I keep my PHP job as a cubicle jockey.

I will start by saying that if your EGT is high now (or hard to keep below 1200 degrees), then don't even consider "larger" injectors for towing. If you want more power, we can certainly do that. Just don't expect to tow anything with more RWHP than what you are making now. The additional power can be used for short bursts on a 1995-1997 truck, but you'll find that EGT climbs like a mad chief when more fuel is introduced. Heck, last week I had one heck of a time with my 1995 while towing 6500 lbs. in 95 degree heat on a tune that is marginally more powerful than stock; I'd venture to guess 40-50 HP, but it's a new tune and I haven't put the truck on a dyno with that tune yet.

I'm thinking of sending in the AA injectors in the 1995 to have some 80% nozzles put on them. EGT is the reason. It's perfectly logical to expect a slight EGT reduction with larger nozzles (to a point) since I don't plan on doing anything else to the stock truck.

Oh don't get me wrong, I know tunes can't do everything.
I can tell you with the few mods that I have and with
your tunes I can live with what I have if I have to.
I am worried about what you stated about towing under 45
because that is 80% of my towing. I think I need to look
into a good Trans cooler.
I appreciate your total and honest opinion.

If you're running a stock transmission cooler on a 1995-1997 truck, by all means get a larger cooler. The stock transmission cooler on an older Powerstroke is barely large enough to function as a power steering cooler. Come to think of it, the stock transmission cooler on an old Powerstroke looks just like the power steering coolers Ford used on the 70's boat cars (my ex-wife's Torino had one).

I have three coolers on my 1995 that are connected in parallel. It stays nice and cool. However, I don't worry about temperatures below 240 degrees.

Synthetic oil also makes a noticeable difference in the transmission.
