I have a predator u7137 for my 05 GC hemi. I have the latest update for the predator v914 something like that. I can not for the life of me find a way to adjust my shift percentages. Will someone help me find this please
The whole reason I bought it was for the trans tuning. It is not under the adjustment section or modify tune area. Where should I look? I'm running the 91 tune.

Thanks for any help with this

Yes, I read through the thread and plan to do my set up the same. I thought I also saw a thread with the downshift adjustments but can't find it now. Are there adjustments for the downshifts?

I will give the DS a shot tonight to get to the trans adjustments. Thanks for the help! I will post results after I get it done.

I'm going to give it a shot tomorrow during the daylight and see how far I get. I can say one thing about it, it helped my gas mileage greatly. I reset and watch the the read out ever day. Guess I like depressing myself. Normally run around 14 mpg on the interstate. today it was reading 18 consistently same road and speeds. If that one area is that good it will pay for itself fairly quick.

Found the trans adjustments. It is a pain but I set it up finally. I will see this week how it plays out. The gas mileage is still showing 3-4 more mpg than the stock set up. I didn't expect such a difference but I'm not complaining. I am running the 87 perf tune with 89 octane. I would like to run the 91 but everywhere here has 87,89 or 93 octane. I will keep everyone updated on the set up and mileage at the end of the week.

brando26- from what I have read, the 87 tune with running 89 octane fuel gives the best mpg. You might be losing some hp from the 93 tune but only 10-15. That is such a small amount it's hardly noticed. The trans set up really helps the GC to drive like it should. I'm happy with the way it drives now, not bogging down all the time. Might tinker some more on it to fine tune later but I'm enjoying this so much ,who knows. Today on the interstate was 17.5 average. That is still up 3.5 more mpg than before the tune. I will keep everyone posted through the week. I did notice in town yesterday the mpg were 14.5. Before they were in the 12-12.5 range. Maybe the trans adjustment helps the GC to run in the optimum zone for rpm's???

Thanks for all the help guys.

I have averaged between 17 and 17.5 mpg all week, much better than before the Predator. I have stayed with the 87 perf tune. Might try the 93 shortly but still thinking about it. If I can justify spending 30 cents more per gallon for a few more mpg's, it will be a go. Working on running the 89 out of the tank right now.

My bad -highway, wish it was city.

OK guys changed the EGR out this weekend. Mileage is up to 18.5 over the last 2 days. This is going in the right direction. Going to load the 93 tune for the rest of the week and see where it ends up. By the way the EGR solved my slight back and forth surging at highway speeds. Also quieted down the Hemi tick at start up modestly. I have the MDS off and it seems to run better and still seeing the 18.5 at 70 mph back and forth 50 miles a day to work.
