Well, finally decided to go with Mike on the SCT X3 tuner with his custom tunes. 87 Tune, 91 Tune and 93 Tune. So far, noticed a big difference with the 87 Tune. Does anyone have experience with all three tunes? If so, which one did you notice the most difference?

Thanks,

 

The 93 octane will give you the most power increase.

Is that what you're asking?

 

For the most part, I was just wondering if anyone noticed any difference between the tunes. 87 vs 93

 

The 93 tune will advance the timing and should add another 15 hp (approx.),

 

You running any tunes?

 

Plug it in and try it yourself. I noticed a big difference. Once my current tank of 87 is gone I'll be switching back to 91.

If your 93 doesn't feel any different than your 87 then there is something wrong.

Is this the response you were looking for?

Don't ask me how I know, use the search button

 

Yes - PHP custom on an Edge CTS.

I have only ever used the 87 performance and 87 tow (no need for the 91+ performance).
