No but did installed a high performance fuel pump 60lbs it does go down to 55 when I hit the nitrous system a 150 shot was not working well so I will try to retune it before I hit it again tried it twice and seems to work good but I know to jet the fuel a little higher than what the Speck's call for 73 nitrous and 40 fuel
I am guessing you are feeding the nitrous off the shrader valve?
Before you use nitrous you have to make sure your N/A tune is spot on, put a colder plug in it and make sure the tune is still spot on, then pull 2* of timing for every 50 hp of jet.
Injectors dont matter with a wet kit, you have to have enough pump.
Do you have a wide band? Do you have a way of data logging?
Make sure you are running enough octane fuel.
A stock motor can easily handle a 175 shot as long as the motor is in good working order and you have the tune in check.
