Has anyone used one of these tuners yet? I haven't seen any posts on these and was interested in the performance gains and switching back and forth from program to program. Any insight would be appreciated.

 

I'm getting mine done on Friday. I'll let you know.

 

i have one on my mustang. and it is easy to use and i can feel the difference when the tune is on or off. not sure on a challenger but if its anything like the ones for the mustang i would say to deff get one.

 

Still waiting for the 6 speed tunes to become available.
I have the DS P U7135 for the Challenger - just nothing to plug into it yet.
A tune should be out any day now.

 

I got mine done last Friday. It gave me an extra 25 horses with the tune. I would definitely recommend it. I got the dyno tune and it took them 7 hours to finally get it done. Orininally, they told me that it was a 2 hour job, but it turned into a 7 hour job. Just keep in mind that this is not a quick job and I wouldn't recommend waiting around the shop like I did. I replaced my headers, exhaust, and CAI so my check engine light came on, but with the tune, they where able to remove the check engine light so I don't have to stare at it everyday now. I do have to hit the ESP button everytime I get into the car which is annoying, but I can live with it. You definitely notice a difference sitting behind the wheel. I would recommend it.

 

The Diablo is the tuner of choice in this forum. There are folks who have custom tunes with the Diablo, but most folks (like myself) just use the Diablo tune based on the octane and whether you have a CAI. Make sure you download the latest tunes from the website. I have heard there is a six-speed tune now.

 

Yes. The 93 octane CAI tune wakes the beast nicely on the 6 speed SRT.
My mileage is about the same, but the throttle response is much better.......
and I'm not sure how, but the stock exhaust sound a good bit louder now - more agressive.
Very nice!

 

Has anyone had problems installing their tuner on the RT?

 

Not that I'm aware of.
Go to their site, create an ID and scan their forum for more info:

I was just curious because I've found out that myself and at least one other person own RT's that the PCM flash was changed by Chrysler and the boys at Diablo Sport haven't been able to get their hands on the new program. I was just curious if anyone else has come across this problem and what the build date was on their cars.
