The Tribonacci sequence $\{T_n\}_{n\ge 0}$ resembles the Fibonacci sequence in that it starts with the values $0,1,1,$ and each term afterwards is the sum of the preceding three terms. In this paper, we find all integers $c$ having at least two representations as a difference between a Tribonacci number and a power of $2$. This paper continues the previous work \cite{DLR16}.
