Help, 10.0 at WOT with n.o.s
I recently went to one step colder plugs, from tr6's to br7's, and with no other change, car is running richer. Before afr's at wot were 12.5's n/a, now they're at 11.5's n/a. Before on the 75 pre-maf shot, afr's where 11.8 ish now the AEM uego pegs at 10.0..
I don't know where to start, could it be the Battery? a Dirty MAF, since i'm spraying through it? Any help its appreciated thanks.. mods in sig

I was running tr6's with the 75 shot no issues, but decided to go one step colder for the added safety n going 125.
Could the maf wires get finicky now that I swapped to a .055 jet?
I bought some maf cleaner spray if that don't work, i'll reroute nozzle just after the maf .
Can I just add the fueling I need with the Diablo intune, considering it will be prob a 125rwhp difference?

The problem is not a dirty MAF, they are heated-element sensors which can be damaged by cold chemicals like N2O. It's not designed to work like that.
Move the nozzle after the MAF, tune it N/A for 12.5 AFR, then tune the nitrous AFR using jets and reading plugs (a wideband also helps).
If you have tuning software you can install a resistor with a relay to trick the IAT and do some cool things

I was just reading About injector offset Vs. Battery voltage table, and I think [correct me if wrong guys] the reason car's AFR's richen up issue its due to the battery, just the other day the battery went out and I found a replacement but its a smaller batt with less cranking power. Could that be why?? I had noticed too when I hook up the intune to adjust or datalog it gives me an error mssge saying the batt charge its low and I have to start the car...

Wideband....
Don't trust the AEM!
Use a non projected plug on any amount of nitrous IMO. TR6 should never be used IMO. They make a non projected 6 if you believe a non projected 7 is too cold (I don't personally think so myself).
I run TR6 or similar on nearly all 10+ compression LSx engines NA and then go colder for nitrous and non projected.
