i'm running nitrous oxide, but sometimes i'm getting detonation on all motor. last night i was pulling into a parking lot and when tapping the gas peddle there was a pop from the other side of the dashboard. timing is set on 10 i'm pretty sure so that doesn't seem like it should b an issue. any thoughts? thanks

 

Doesn't sound like detonation to me. Backfire maybe?

 

read the plugs, they don't lie

 

detonation in N/A form sounds like a bunch valve noise clacking away.
with nitrous detonation sounds like a big BOOM!!!!!!

kinda sounds like you are getting a lean backfire.
