look in what range you are getting the knock and add fuel there. Some people have added up to 20 in some ranges.

it might take a little time for your truck to adjust, but that's normal. You should see a big difference between 87 and 93. 93 is the more aggressive out of the two, and 87 is more like stock. Run that 87 out of the tank and get some 93 so you can use the 93 tune. You'll be glad you did, just get ...

I also agree here. Something is not right to begin with. That's pretty low HP for that Hemi. My 6.1 was also knocking bad with the stock tune. But when I hooked up the Predator and "fine tuned" the 93CAI tune, and got rid of all that knocking, the difference was amazing! "Stock out the door" I could ...

the stock t-stat is 203*(roughly) and you swapped out for a 180* t-stat, so you just drop it down 20* or so from where it is already set and you'll be fine. I have mine set up at LS 185* and MS/HS at 188* with a 180* t-stat. But like DGatzby1 said there are lots of opinions out there, so do what ...

it doesn't matter which one you have, the CAI tune is for any CAI

the catch can, and getting rid of the knock will make a ton of difference. just get ready to buy tires...

But how do you get rid of the knock? I am having the same problem with my GC SRT 8. I have a post going elsewhere but I 'm not understanding how to correct the problem.

run a log and look ...

You just need to go through the Shift Modes and find the one that works for your car(choose a mode then take it for a test drive to see if it works, if not change the mode and try again)
The fan settings need to be dropped 23* from where they are set now to take advantage of that 180* t-stat

makes sense to me. I get great milage in my 6.1 when I drive normal, but when I get into that throttle it drops pretty quick. If I wanted a car that gets great milage I would have bought a Honda...

something is not right here... I get 17-24 depending on how I'm driving, and I have the 6.1. Post a log so we can see what's up.

You need to set your gears to what you actually have in the car. Changing the setting without physically changing out your gears in your rear end will cause damage to your car. It's not the tunes, or the Predator that's messed up....

Leave it alone, it's still a CAI so you are good. I love my Airaid! Did you get the scoop adapter?

NOTE: I also connect my DS Predator to windows XP running on a virtual machine on my mac using a USB to serial converter with no issues. I've not tried this yet on vista.

I'm going to try that. I love my mac, and it's a lot bigger than the Dell mini I use. I just don't want to install Windows on ...

get a CAI, it's worth it compared to the stock one.

you can get a CMR tune through email from shops on the internet. Just do some research before you spend the $300-$400
