I need to retard my ignition timing so that i can make 20psi with a gt28r without detonation occurring .... I know bb tuning when they existed used to sell tdc sensors with 6 deg retard on them .... but i cant find them anywhere now ..... CGB sell em but with 6deg advance only ..... Anyone Help me ???
Also does anywhere still sell the adjustable timing sensor if i cant get the above ..... Cheers.
