First I would like to say to Mike and the rest of the Diablo Gang...EXCELLENT PRODUCT and unparalleled customer service. It's great to see someone still stands behind their product...keep up the GREAT work.

As to my issue. I have a 07 Charger SRT8. I received my Predator last Friday and installed the Performance 93 Oct tune for CAI. I raised the shift points and the rev limiter(+400), changed my tires size to adjust for the 22's I have on the car, and reset the TCM. The car was a beast and I loved it. I made some runs just to get a feel of it. Yesterday I changed the rev limiter(+300) and shift points via Quick adjust. This morning I noticed that my throttle response feels like it was stock. It is no where near as responsive as it was. Do I need to go back to stock and reinstall the 93CAI Tune again to get my throttle response back like it was when I initially installed?

Also, what is the rev limiter on a stock SRT8. Is it 5800 RPM? I changed it to +400 then to +300 but I don't know what I'm adding those number to. I know the raised shift points shifts at 6400, so I want to be sure my rev limiter is a tad higher than that.

I do have the r17 version on the Predator.

Any assistance is GREATLY appreciated.

The throttle response should not change on its own.
I would reload the 93 tune to be sure it is there.

As for the rev limiter, it is raised in the tunes so it will not kick in before the 6400 rpm shift points, so raising it by 3-400 rpm puts it around 6700-6800 rpm.

Thanks

Thanks Mike! I'll go back to stock and reload the 93CAI Tune this afternoon. I REALLY hope this fixes my issue as
I loved the throttle response I had after initially installing the tune.

No need to go back to stock, just load the 93 tune.

Thanks

It seems like when u make any changes u must install 93cai again, or it's lost, does anyone have the same thing . also still having issues with autoshift, can't use disable at all, and with autoshift on it gives me check engine light with something to do with transmission now. any fixes down the line mike?
