So I recently added 75% nozzles to my 175 warren injectors. The truck ran great with 175/stock but now it seems to have a few issues with the 75% nozzles added.
Is it normal to have a slight chug at idle once the truck warms up? Not really a miss but more like a choppy idle? It does not feel like a miss at all and goes away once I give it any throttle
The motor does not like to be lugged... seems to run choppy
I am having egts issues even with new tunes. I tried running a tow tune and the results are all similar.
- Idle = 350 (normal)
- WOT 0-80 = 1400 (normal)
- Cruising at 75mph = 950 (way higher than my normal)
- 1/4 throttle from 0-60 = 1200 (way higher than normal)
Boost levels all seem normal
Back pressure is also normal
With the new tunes it is not overly smokey (like it was with the 175/stock tune)
vgt duty cycle is acting normal
Truck runs and drives great
No weird smoke on startup
No weird smoke while idleing
I know the atomization is not as good on 75% nozzles... but do those numbers sound way too high?
I hate asking tuners for tons of different revisions so I was hoping to figure out a baseline or if something else is wrong before I keep asking for revisions.
