cank...no there is not a setting to blow up your tranny...the 3865 is a great choice and is pretty much the same look at posts above and see the diff....and also the posts above have info where to get it for the best price...truckcustomizers using winter10 code....

 

This is probably what I am going to go with. I am assuming it stores your stock settings so I can switch back to stock when I take it back into the Stealership ? JusJay you have 4.7 with the chip . You Like ? Also this is a dumb question Im sure but I have 4 wheel drive this does not make a difference ?

 

Man i really wish there was trans options for the 03's. i love my 3865 but not being able to change my shift points blows! if i were to change my gears to 4:56's do i have the capabillites of doing anything with my sc?

 

i got the 3865 about a month ago. definitely worth the money. works great. yes you can revert back to the stock tune at any time.

 

AAHH so no shift point change with the 03. Damn I hate the gears on mine

 

Is there any info on the testing for the '05 Hemi's? Any ETA?

 

Well I just put my CAI on and WOW ! Night and day difference. If I'm this excited about a CAI then I am sure I will be like a gitty littlle school girl about the Superchip

 

theres just no trans tune options on the 03 and older...but you still get the regular gains as we get right now just in the spring well have full control over our trans....fingers crossed for the 4.7l guys that it will be released when they release the hemi stuff.....

 

I see on SuperChips website My 2005 4.7L they asked 4.7L or 4.7HO. How do I know if my 4.7L is HO?
I all so see Fuel Economy Calibration. What dose this do? I have not purchased 3865 yet.

 

still testing but things are going good
