Was dissapointed with agi performance in genesis mode. Looked around and found out the spring is the culprit. So tonight decided to try something to replace it some suggest using the pin from clearomizer as I have none from giving it all away I went with another suggestion. So I remove the pin in the carto shave it down a little, and bam the genesis mode works awesome now. Not sure how much voltage drop is still there but it was massive improvement over original spring connector that's for sure
