Hi guys! So i recently bought a ionbox prc AIO sxk with a dna60 chip. I have a boro with a 0.54 resistance inside. Even with a fresh New battery bought a Day ago (vtc6 3000) the mod dont do the watts i pretend. I program to 35 watts but only deliver between 20/26 watts... I dont understand..Also the battery indicator is always blinking dont know if its normal. Ive done everything on escribe twice, factory settings, New profiles, etc but continues the same. Anyone can help me? Or the chip has a defect?
