nice thread. i just joined this forum, alot of knowledgable people here. im planning on ordering a gryphon next wk. and im looking for some help as far as custom tunes. Currently i have a 40 series si/do flowmaster installed but after the gryphon i plan on adding more mods.
i want to take advantage of my exhaust/ future mods on all 3 levels. im thinking of doing a 87perf/econ tune, custom 87towing tune, and a custom 91+ tune for balls to the wall action.
do i need 3 custom tunes or should i leave the 3rd alone? im pretty sure i want a 87perf/econ tune and a custom towing tune for power up hills etc.
