What are your opinions on adding MSD ignition box, coil, wires to a slightly offroaded 98 cherokee with stock powertrain, 3.5 lift on 31's?? Looking for better fuel economy, smoother idle, quicker response. I do pull a trailer loaded with atv's quite often too. Just wanted to know if people on here run MSD much or if Accel or something was better in your opinion.
Thanks
