No it is non adjustable.
driving along about 35mph and put it to the floor
Sounds like i have the wrong combo ,at 60mph mine doesn't throw me in a tail spin......... I installed the TE61 with 9/11 and adjusted the chip to max fuel. It wanted to knock all the time so i took it off and put the ta49 back on. never did figure what was wrong. left the 9/11 with the ta49.
