[QUOTE="dseitler, post: 909249, member: 14112"] I'm running the SPE also. I want to give a shout out to there customer service, second to none. The Trans is very aggressive at first but levels out after a couple of days. The Tune is very strong and the power is great for a CP4 pump. When I was running the H&S box tune I would run a constant 14.7 1/4 mile with ease. I will know next Friday on my current HotX tune times. If I extend more than a 1/4 mile and stay into WOT the truck drops rail pressure and shuts down running the HotX tune. I'm researching now my options on the fuel rail dump but not sure if I want the dual pump setup. The truck weights 9180 lbs with the set up I'm running now. I'm concerned the Trans will be next if I go to the dual pumps. I can here the clutch packs Howls now with my current set up at WOT. I want to talk to SPE on Monday and see what they think the next step would be. [/QUOTE]
