So i have a vamo v5 and a kayfun lite. 30 wire and 2mm silica. I have the same problems with my protank 2. but i dont use it much so i want to focus on my kfl. I just rebuilt a new coil, 1.5 ohms installed it, dry burned it, added juice, waited 15 min turned it down to 5 watts. Tastes good first 2- 3 vapes after that it tastes burnt, even at 5 watts.. I took it apart and dry fired the coil. Refilled it, same thing. I then built another coil same ohms but this time didnt preburn my wick, just the coil. Same issue, burnt juice flavor after a few minutes of vaping on 5 watts. That was with MTB vap juice. I tried again new coil, new wick, different juice, this time from mad vapes. I was able to start slightly higher but even anything past 6 watts gives me a burnt flavor. When i first got this setup I was vaping all my juices around 7-9 watts, now i cant get over 5. I want the clouds that came with the extra watts. Where did it go and why can i crank my watts up anymore?
