Hey all,
As you may or may not know my truck is in Guantanamo bay and the only gas we have there is 87 octane, nothing else. I was going to buy a Cortex but read up on the predator real quick and their description says that it works great for 87 octane as well as premium. So here is my question to you. Would the Predator or Cortex best be suited for use with 87 Octane?

 

dsp is for hemi only...

 

I probably should have made sure they even had a 4.7 version. Damn my bad, completely spaced on that one.

Well that being said would a Cortex even be worthwhile or should I hold of to be back stateside where I have different fuel choices?

 

the 3865 will work great for you. look at the sc sticky at the top for some more info

 

yea i agree with bullet, if i were you i would get the sc flashpaq, cortex is prob alil overkill for a 4.7

 

After I looked into it a little more I'm gonna have to say that I'm agreeing with ya'll plus it saves me a little money. Thanks for the help.

 

i have the hemi..which one would be the best for MPG..stock 5.7 right now

 

the cortex only offers a tranny warranty if the truck is below xxx miles and black and gray case.... over the 3865...puts out the same numbers....i went thru this with the guys at s/c when i had my phenomenon with the stolen cortex....

 

Kotex is a feminine product anyway, get the 3865 for the 4.7L. DSP for the Hemi.

 

cortex works fine on the 4.7l also but for the money get a 3865...its the same thing minus pertty black and gray case....and tranny warranty....
