It says the pulley tune is for 12-14 PSI Max ! I would think with a 2.80 you should have it dyno tuned ,and store it in the Predator. I am no expert , all I have used it for is loading the performance tune. I would ck with your local tuner and see what they use, Predator or SCT.
is the predator unmarried and does it still have the stock tunes in it or does it have custom tunes in it......let me know soon might be interested in buying QUICKLY!!!
