today i test the primary resistance on the coil pack and all 3 failed. specs called for 0.3-0.5 ohms of resistance while cold. i'm sitting at 0.6. i also test short to ground and that is fine.

do you think i need to replace my coils. i'm trying to break the 600rwhp mark and i want my igniton sytem to be up to par.
