Sweet, thanks johan. Who would of thought it could be that easy

I just got dynoed recently and the (Certified DSP) tech made adjustments to fuel and spark and such to the 91 CAI canned tune, it's wonderful compared to just the canned tune alone.

Now I've come to a crossroads, I'm coming up on 12000 miles service and I want to save this tune . . .

How do I go ...

Here's a simple rule:
On a 91 tune, use 91 or better. On a 93 tune, use 93 or better.

It won't hurt anything to run better octane fuel with a lower octane tune i.e. 93 gas with 91 tune.

In fact, that is why some are getting better numbers, running it this way, because some fuel is just crap no ...

I'm stuck here in Colorado Springs, CO and don't know what if any is some quality gas. We've got Shell, Conoco, Phillips 66, Diamond Shamrock, whatever 7-11 is selling, and a few "mom n pop-type" others.

Anyone have any suggestions or should I just trial and error it by the tankfull?

Thanks

any thoughts on what to set the fan settings at with a 180* t-stat(a/c on and off settings)?


I have an 08 Charger R/T, with a K&N CAI, Jet 180 thermo, and 91 CAI tune (Ver. 9r07)
