So you're getting a little bored with the stock performance of your 08-09 Challenger SRT8, R/T, or SE. After searching the internet & perusing our site you've decided that a Tuner (Programmer) is on the short list of "to do" items. We felt the same way, so we added a Diablo Sport Predator Tuner to our 6.1L 08 Challenger SRT8 . The part # for the Diablo Pedator Tuner we used is DST-U7135 & it works on the following 5.7L HEMI or 6.1L HEMI equpped Dodge vehicles:
05-06-07-08 Chrysler 300C, 06-07-08 Dodge Charger, 05-06-07-08 Dodge Magnum, 06-07-08 Jeep Grand Cherokee SRT8, 08-09 Dodge Challenger SRT8, & 09 Dodge Challenger R/T
If you have an 09 Challenger SE, use Diablo Predator Tuner part # DST-U7136
Loading the tune is super simple, so I won't bore you with the details. We went for the gusto & loaded the 93 octane tune & modified a few of the parameters such as Autostick** function, rev & speed limits, & tire size. All you have to do is find the DLC (Data Link Connector), plug in the Predator Tuner & folow the instructions.
Just a side note, one of the first things the Diablo Predator Tuner will ask you to do is turn the key to the on (run) position. My inital reaction was, "There is no freakin' key! How does this work?" The answer is quite simple. Without pressing on the brake pedal, push the start button twice & it will set the ignition to the on position. To set the ignition to the off position, press the start button one more time. Pretty nifty!
After we loaded the tune, it was time for a test drive! After we put the wheels on our Challenger, you could definately feel the decrease in performance from stock. After loading the tune the Challenger had its pep back! We used the Challenger's built in 1/4 mile performance meter along with an iPhone to measure the performance. The previous best for our Challenger was a 14.02 standing 1/4. With heavier wheels & in the heat of the day the Challenger responded with a 13.95! The car was much more fun to drive & had a much imporoved shift feel.
Overall, we feel that the DiabloSport Predator is a worthy mod & should be one of the first you perform!
**The stock Autostick will still automatically shift up to the next gear at a ceratin RPM. The Diablo Predator Tuner will tune that out & allow you to manually hold whatever gear you desire. When you elect to modify the tune, under the Transmission header there will be an Autostick option. Under that optin you will see Mode1, Mode 2, & Mode3. These Modes will allow for full manual shifting with the Autostick when in the manual select mode. Try Mode1 first. If the car still automatically shifts to the next highest gear when in manual select, try Mode2. If Mode2 doesn't work, try Mode3. One of the 3 will work for your Challenger!
