Yep, Dustin set me up with that same setup but I went with the 60% over injectors. I was there for the pull but my truck was under the knife with te cp3 and injector mods. I would have loved to see if I could do the same with 60 over.. But I'm not nearly taping into my fuel so it's a good possibility..
For 543hp to make sense your race weight would have to be about 7500 lbs. Most crew cabs are more like 6900-7000, which would put you right around 500 rwhp, right at your uncorrected numbers. Regardless 500+ on a "stock" truck is always impressive.
