Canned Tunes VS Custom Tunes
 

I have a 97 f150 5.4 4x4 and i got the 93 octaine performance custom tune and i cant really tell a big difference in the canned tunes and the custom tunes, is it just my truck or am i not doing something right or what?

The custom tunes will not have the same night and day difference as the stock to canned but if it doesn't seem like much of a difference, go back to stock as a comparison.

Put it back to stock......

Disconnect the battery....

Turn your headlights on.....

Go do something else for 15-30 minutes......like clean the tb and maf........

Turn headlights off.....

Reconnect battery.....

Drive with stock tunes 100-150 miles......

Then load the custom tune again.....
