i agree that there needs to be a sticky with "recomendations" for starting points. I have searched this too many times and its frustrating.
Also there should be mention about running too cool as the oil temp may not get hot enough to burn off condensation.

Just a FWIW, I had problems with the tunes. Updated same exact update then it worked. Is it possible durring data transfer the data gets corrupt? I did play with the baud rate but dont know what it does or that effected anything.

When going to modify spark I get the message that it must be done in same amounts
I assume it means that the adjustment must be the same in MBT as well as reg in the same band?
Or do all the MBT sparks have to be the same in all bands?

Mike, Thanks for the reply. Number 3 still does not make sence to me. Running 93 octane and te 91 tune has higer knock values than the 93 tune. Would not the 91 tune benifit or at the very least have less issues from higher octane?

Now the next question is what do I do now that it seems both canned ...

2010 Cahllanger 5.7 auto. Preditor 9r21

Having problems with canned tunes having less performance than stock.
Ran Sunoco 91 oct with 91 tune. Vehicle had knock (14) so I called and was told to run 93.
Ran fuel out and did Sunoco 93. 91 tune high knock, 93 tune moderate knock. Stock running great
