2017 Challenger R/T Magnuson 8psi tune

[11challenger]

Magnuson revision 2.28.21 8psi timing adjusted pe.hpttesst 22821.hpl
The car is running pretty well overall, but I feel like I may be down in power to what 8psi should be on this engine.
There is a Snow Performance Stage 2 water injection kit installed, with a number 5 nozzle coming in at 2psi and maxing out at 11psi (so it never hits full steam, so to speak) with summer windshield washer fluid in the tank.
Attached is the current tune and a log file. I do not have a wideband hooked up to it yet, that is coming next week.

It's running a bit lean at WOT

PE calls for low 11's.....will verify once the wideband is installed.

Do you ever have issues with the meth spraying at part throttle sometimes, or at too low of an rpm? I'm running basically the same setup (snow kit and 8lb maggie) and was thinking of running the smaller nozzle to not quench combustion when I'm not actually at WOT. Or is the #5 still small enough to not give any issues? I have my boost restrictor out btw so boost is instant

Any verification for us.. have you worked on the ve tables? What injectors are you running

Don't make anymore wots until you have wide band. Your PE is not really good. it is definitely not at 8 PSI according to that KPA. Narrow bands should be maxed and they don't seem to be. So you are lean!!! If I get more time I will give it a look

[11challenger]

The car was running lean. The PE tables are bumped up quite a bit from this tune, which helped significantly. The water/meth kept it cool and together I would imagine.
I can add a new log soon, as I haven't checked on this post in quite awhile.

I find the #5 to be fine for me, when ramping the injection rate up to full spray at just above the 10psi range (meaning it never goes full bore) when I am running mostly water. I haven't mixed up a true meth/water batch just yet.
