I have a T/A already with my timing set where I want, and have my 4.10s and a speedcal on the way. My question is when I go to get tuned by Jerry, will he be able to just leave the timing alone and leave it to where I can adjust it myself with the adjuster? or when I get the superchip will I no longer be able to adjust the timing? Granted I won't be adjusting much, but would rather be able to do it myself than have it set with a chip.
