Spikes at high mghz belt tension

Any idea what this means ? On lower frquencies my peaks seem to almost match, should i still try to tension the belts better ? Thanks

Sorry missed your reponse. Running af 76 herz for both belts for months now. How do you know it is too tight by looking at that chart ?

those spikes say you're running at 175+ hz
