looking at your dyno gragh and i can see that your car going rich on bottle , and IMO that thing needs to be fixed up and i'm sure you'll get a better results then

HOW .. ??

ok , here you go

1- check the bottle pressure if it's above 950psi or not , if so try to resize your fuel jets to get a better spray tuning

2- ok the pressure is fine 950-1050 psi , now make sure that you are using the right jets for your system (what ever your system is) make sure that you are not runing any jets related to other system or other kit

3- if everything is fine and still your system gives you the same gain , get your self other kit which is not cheap brand or universal kit

last thing i would like to say is somthing related to the camshaft specs. , it's known that the wider LSA the much friendly with NOS
and you got 112 LSA and IMO no wounder losing some hp gain when spraying

good luck buddy
