i think you will need to use the predator to set the paramaters when you get on the juice like making the A/F mix richer and adjusting the timing so i would use the predator tune
you can but then you get doggy performance,get the msd then you can have the best of both worlds,really good timing and a box that fires heavy spark cycles and wont blow up a good engine
sorry i wasnt clear as i should have been you advance the timing to drive daily and when you are ready to spray set the msd to retard it for you,alot faster than loading and unloading your predator tune,just pull over before race and set your dip switches or on the new ones they have pots on them to turn another words leave your tune alone,oh and dont get a dry system kit
