i forgot to add. the det sensor looks for a very small range of freq. i doubt its because your running mechanical setup and no BS's. the vibration from removing the bs's would not be in the freq range. now if your a tooth off on your cam gear or your getting pre.detonation it very well may be. If your boost has not decreased from 10.5 to 7.5 id say no(as long as your stock ignition system and boost sensor is in tact)
