Ok so i have an 03 ram 2500. i have a bd super b turbo, ats exhaust manifold, 90 horse injecotors, fass 150, custom exhaust, intake and bd air arch. The tranny was rebuilt with a bigger torque convertor and shift kit. I am going to be hooking it up to the sled in 2 weeks and want some advice. It is an auto. What rpms should i leave at, should it be in 4 hi or low, and what gear like d, 1, or 2. Need some advice. thanks.
