Its a 94 del sol with T3 at 8psi with frontmount, 12:1 fmu. Im running 14 degrees ig timing with NGK BRK7E plugs(.030 gap) and 1 Degree of retard for every pound of boost on my msd btm.... Im still hearing a little bit of what i believe is detonation... Why, is my question. I shouldnt even need to use the BTM at 8psi. Could it be that my plugs are bad? Would that cause detonation?

 

someone?
