first no 93 octane gas here i have some ping how can i adjust? Also i have a 180 tstat and want to adjust my fan temps! Any suggestions? Also any other adjustments will be welcome!

Make sure you run good quality fuel before adjusting the timing down, we recommend mobil, amoco/BP and sunoco. The fan temps are dropped 30 deg from factory setting in the default Predator tune, i would drop them maybe another 10 deg across the board for the 180-tstat.

ok i adjusted the mans another 5 degrees! I ran chevron 91 octane in the car. I will try mobil next in it. But if i were to adjust the timing can you give me the parameters to follow. i am new at this but catch on fast and have a civil engineering background!

Thanks for the awesome customer service also!

Before you decide to adjust timing, monitor live data to see if there is any KR, if not, there is no need to pull timing.

Thanks
