Wideband Tuning

[griff364]

Good day,

I've got a 2011 GMC Sierra 1500 with LT header, 3" exhaust, and a k&n intake. Soon installing a cam, valve springs, pushrods, and trunion kit for rockers. I am using the diablosport inTuner with which to tune.

On which octane should I tune my wideband to? I've been reading and getting a general consensus of 13.0 or 13.1

I am also going to supercharge it in a couple years. What will I need to tune it to then?

Let's try to cover all bases:

Naturally Aspirated:
87- ?
Mid grade- ?
Premium- ?

Forced Induction:
Mid grade- ?
Premium- ?

Thanks in advance!

Same A/F ratio no matter the octane, change timing accordingly. Sell the POS Diablo

I just bought it!! It at least lets me add fuel where I need to and change the TCM...

what's a good number to tune to? I've been hearing 12.6-12.8
