well installed a FI s472/83/.91 T4 on a heavily ported pdi T4 manifold with some cpp150's. SO here's the problems,while cruising down the hwy at 80mph i am running around 2200rpm and making about 8psi, rp is 16K but egts are 1100-1200. Smarty tntr, latest update, running sw5 tq1 tm3 rp1. i have changed a bunch of different settings with the smarty and nothing really changes. When i try to climb a hill at 70 or 80 or any speed really the egts will climb to 15-1600 easily and wont cool off. While climbing the hill there isnt any smoke, have a real hard time getting from 10psi to 20psi and egts just skyrocket. On flat ground if i get the charger lit in 3rd gear with the tc locked around 2200rpm then i can build 48psi, rp holds 25K once i am over 2500 rpm or so, but again egts will hit 1600. I have looked everything over, no drive pressure leaks, havent pressure tested the system but i had no leaks prior to the install and only changed one boot with a brand new one.
So any insight as to why it is doing this, i was thinking tc but that shouldnt have any effect once the converter is locked, right? The manifold is wrapped and sometimes it will take over 10 minutes to cool off under 400F. While cruising at 80 i get zero smoke or haze, just high egts and crummy spool. Could low fp to the cp3 cause this. i know i need a bigger cp3 but havent seen a rp issue while watching the gauge, maybe i need more rp down low to help atomize the fuel better.
Well hope to figure this out, lets hear what you have to say.
Truck is current and in my sig.
