I don't think you will see a noticeable change in performance going from 3.55 to 3.73I see you have 3.73's. I'll be going from 3.55 to 3.73's this week. I wonder how much of a difference I'll notice
Yeah those injectors were tough to get in. I thought I had the wrong injectors for a while. I lubed them up and shoved them in there and it's all good.

Your going to notice that your crossing the traps @ 6100RPMs lol. But that may not be THAT bad for you since you probably dont have valve float.
If I had 3.55s I wouldnt swap them in for 3.73s if I were you...thats coming from a 3.73 guy.
this is what I get with 315/35/17 rear tires like I have and the T-45 in 4th (99-00 trans...4th is 1.0-1 like the TR-3650)
Corral RPM / SPEED / GEAR Calculator
Engine RPM: 6000
Vehicle Speed: 122.897026299583
Read End Gear: 3.73
I was crossing @ 120-122 and showing 6000-6100RPMs. I have checked mine with the EEC digital read out to over 5000 and it stays within 100RPM of accurate.
I know one thing, on the dyno my car floats the valves past 5800...and my car was laying over badly about 150' from the end of the track.
EDIT: I even tried it with the stock 245/45/17 tires...same thing 122.8. Do you have 05+ stang size tires?
