U7137 Issues with 09 Ram Hemi

[jws8308]

Hello All,

I have a 2009 Dodge Ram 1500 HEMI and have been using a Diablosport Predator U7137 for a couple of months now. I have the high performance tune installed but have noticed a lag in shifting among other performance issues. I always use premium fuel and have installed a K&N Intake along with a Magnaflow Cat Back system. The vehicle does not see much travel (I only have 3900 miles on it and I bought it new).

Whenever I take the truck to the dealer for service, I always place the vehicle back to stock and when traveling on the stock tune, the shifting issue is non existant and there actually seems to be more power, believe it or not.

Any ideas, suggestions........Help me please, lol.

Also, I have searched through the options but could not find, is there a way to turn MDS off. I hate that system so much, especially when driving around town.

Thanks again,

Jim

To turn off MDS go into the performance tune adjustments and scroll down.

what Crom you using? if you don't have 9r13, update to it. could help.

I was using 9r12, just updated to 9r13.........nothing noticeable in the update. Shifting is still very, very stiff and power seems lost.

I must of missed the MDS thing. I thought maybe it just wasn't an option for the 09, but I will look again.

you should have an option to turn MDS off in "modify tune". if not, I can turn it off in a custom tune.

power loss is backward, you should gain power with a canned tune unless it is the 87 octane.
