Do the SC Cortex and Edge EvoHT give the same gains? i cant find info about the edge.
Are there any good guys to do SCT tunes for the 4.7 and with the sct can i calibrate the speedo or change shift points from the programmer?

 

SCT hands down, thats what i currently have and love it. i had both superchips and SCT and sct is better. email hemifever@aol.com if you have any questions. its $265 for 3 canned tunes and you can give him 100$ more if you want custom tuning, which requires an air fuel gauge. thats the option i have. a must need if you do cam swaps or intake manifold swaps, or boost. hemifever cant touch our trans but you can do the tmr mod and sonnax which are good alternatives.

 

Thanks for the info, my little truck lights up the tires too easy im not sure if one of the previous owners did the tmr mod but ive hit the rev limiter while doing a brake burn and never had an auto do that before.With the SCT can you calibrate the spedo for different sized tires?

*edit* i looked at his website its cheaper to get the sct from him with 3 canned tunes than to buy an edge or superchip from ebay, im deffinately going with hemifever once i find out if i can change tire size

 

he cant change tire size.

 

thats mostly what im looking for, i dont plan to do anything besides cai and a catback so maybe the superchip would be better for me.

 

Thats what I have/had on my truck. The SC cortex. Its worked great for a standard tuner.

 

For $25 the dealer will change tire size for your speedo.

 

I purchased the EvoHT tuner for my 01 2500 V8. Updating the tuner i'm getting all these not "valid" and error Uploading EEprom file. Can anyone help with this?
