Sled pulled my '06 F250 last night, first time with this truck. Started off in 2nd gear red-lined it right away, although I backed off and held it right around 3200-3400 rpms and I sware that it even studdered a couple times in this rpm range; shifted into 3rd after a few seconds and had no problem while in the low 3000's rpm range. It sucked b/c I was really hoping to hold it at 3500. Could my Edge Juice Platinum have anything to do with this. I pulled in level 3 in order keep my egt's under control, which did great holding under 1200F the entire pull. These are the only mods to the truck; Edge Juice Platinum, full length 4 in. exhaust, EGR delete, and ARP studs. Really the only thing that I can conclude is that it has to have something to do with the Edge (such as % backdown since I hit the rev. limiter at first and was close to it the whole time in 2nd). Isn't the stock rev. limiter set at 3,650 rpm? Is the rev. limiter a soft one where is starts limiting some say for example at 3400 and then a little harder at 3500 and then the hard limit is 3,650? Maybe that's what it was. If so, it's got to go before next years pulling!
