Is a backfire common to LT5s? - ZR-1 Net Registry Forums

When I am going 30-40mph and let off the gas to downshift, I hear one distinct backfire then that's it. Is that common?

The backfire is in the defueling in the chip. Take the chip out or have another done and tell the tuner about the problem.
