I have uploaded the 87 Octane tune but i want to get the best out of the predator that i can. If you can guide me in selecting the right parameters for my modifications and needs or guide me on how to acquire a custom tune, I would greatly appreciate it. I will attach original factory tune, Thank you

You will need to run the tune for about 300miles. Then do some datalogging and make sure to adjust your injector pulse width. Read up in the stickies! Then you will want to adjust your shift/transmission settings to your liking. Then do a constant load log and save it to your pc, then a WOT log and save to your pc. Then contact Diablew for a custom tune. Im getting an average of 16mpg around town and almost 20mpg while on the freeway with the 87tune and my adjustments. It does run stronger as well. Im in the middle of doing some logging so I two can get a custom 87tune done. Hope this helps some?
