I wondered about that myself, so i just went ahead and bought one. I got it a couple of days ago, but it has been raining a lot here, so i haven't had a chance install it and try it out. I also got a lower temp thermostat, i will install them next weekend and will post my results. By the way i have a 2010 srt six speed.

Nearly everyone says there is a very noticeable improvement in performance over stock. I feel the same way - did the 93 octane/CAI tune back in Dec - "wow" was my impression driving it the first time after the tune. I still feel that way every time I drive it. Interestingly (for me at least), the Predator really doesn't make any drastic or "big" changes to your car's computer settings. It basically "optimizes" a number of things in fairly small ways (if using a canned tune). Collectively, all those little tweaks to the programmed settings adds up to noticeably improved performance. Some posts have dyno results before and after - and the charts show genuine gains. You guys will probably like the results on your own cars.

I have a 2010 R/T Auto and just installed a MOPAR Long Ram CAI and got the predator yesterday. At first I was very disappointed as there was no noticeable difference...BUT, I still had about 1/8th tank of 89 octane when I filled up with 93 octane. Put in the canned 93 octane CAI tune and drove around last night without noticing a difference. After driving today it was as if the car suddenly woke up and I noticed a big difference in response in the accelerator! Before in auto mode I hated that lag that was there from the MDS, now it is gone and the car seems to have jumped to life. Very happy camper! Still wish I had a 6-speed and drive more in manual mode with MDS off but mpg do suffer. Oh well

Well, i installed the 91 cai tune in my car yesterday, being that i only have access to 91 octane fuel. Here are my observations, the car feels way more responsive below 3k rpms, when before it felt kind of sluggish to me. I used to feel the car jerk a little at low rpms, that seems to be gone now. I haven't had a chance to go wot, so i can't comment on that. All in all i feel that it was worth my money, not to mention that will be able to change the fan settings when i install my low temp thermostat, it's definitly worth it. In my opinion i say go for it.:thumbsup:

I am running the 91 octane CAI Predator tune on my 6 speed. When I installed it there was a noticeable, but not dramatic performance improvement. I did notice that the RPMs seem to run a little lower at speed than they did on the stock tune so I modified my shift points a bit. I also installed the 180 thermostat and reset the fan settings. It runs alot cooler now although EVIC suggests I gave up approximately 1 mpg for the cooler temps.

I went with 189 for the low speed and 199 for the medium/high speed. The predator requires you to set it for both AC on and AC off so you need to go through it twice. Its also worth noting that you will want to go back and verify that your change was saved as I had one that I had to do twice before it took.
Some guys are setting them about 5 degrees cooler, but my research suggested this was a happy medium. Today was in the upper 80s here and the temp was about 200 rather than the 215+ it ran with the stock thermostat.
