I have the edge box with attitude and have been thinking of getting the unlock code. I'm planning on getting a valve body in a couple of weeks and a tc over the winter and by next year having a complete transmission built and a lot more mods. Right now I'm running level 3 all the time and have only been on 4 and 5 a handful of times. I have pulled the truck 2 times on 5 and was just wondering if having level 6 would give me any advantage or would I be just shortening the life of the transmission that much faster. Just wondering who has the HOT and if anyone is running it on a stock transmission and if there are any problems. Any input would be appreciated.
