im new to tuners. i bought one off amazon and im at a loss. i thought they were pre programed for 87 89 and 91 octane. and were able to change shift points in the transmission ect ect.the one i got is a sct x3. any info would be great

 

It depends on which one you bought. If its a x3 3000 model there isn't any preloaded tunes as its custom tune only, and the sf3 3015 does have preloaded tunes and can do custom tunes as well.

 

the one i got is a 3015. i updated and all that. but still no tunes

 

If its 3015, it should have preloaded tunes. When you plug it into the truck and sect program vehicle, strategy tune, what does it say? Also which year and engine do you have?

 

it asked me about the engine size, and octane level. 87 or 91 is all i got. its a 2002 f150 4.6

 

i found the problem.. amazon advertised somethin different..
