Need help please going back to stock gear ratio on predator

Guys, need your help. I was messing around with my predator to see what gear ratio options are offered. I went to hit escape and somehow screwed up and selected a different ratio. How do I go back to stock? I went out and then went back in and selected "no change" as there is no 3;08 option. There is a 3:07 ,but no 3:08. so I'm not sure if selecting no change,left it at whatever i hit buy accident or if it takes me back to stock setting. Please advise as I'm feeling real real real real stupid right now.
Thanks
DW

On whether your change was actuially stored in the PCM.

Either way, update it to 3.07. That's close enough to the stock value.

I would reload your stock tune ( backed up in the predator); then reinstall the predator tune.

that's what i ended up doing and all is well. The above post mentioned stock gearing of 3:06 but I thought it was 3:08.
one thing i can say though,is what a change going back to mystock tune and driving it for awhile.I knew the predator was good,but my car really took to it well.When i put my predator tune back in,completely different animal,i love it.

Major difference over stock.

You can change gear ratios with a DSP for these cars? Im new to the SRT8 world, hence why Im asking.

Not exactly. What he is changing is how the computer interprets the gear ratio so the spedometer is correct. This comes in handy should you switch to different size wheels or tires.

actually they added this feature, specifically for changing rear end gears. since there is already an option for changing tire sizes.

yeah, when I first got the predator I said the same thing..."wait, that can't be possible, unless they started computerizing these things since I last swapped gears in a car". I of course realized my blunder as soon as I stepped on the gas with my new "computer installed 3.55s".

Turns out it alters more than just the speedo
