I pulled this season in south-central pa area. Just have traction bars, pulling hitch, sleeves, and a tony burkhard brace. Lift pump and efi live for power and I was usually top 5 at the local RWYB events. The last pull of the season was a big end of the year event that brought out a lot of stock appearing modified chargers, injectors, and lockers front/rear. The truck still seem to do well, I got 7th outta like 30ish trucks. A good setup will take you far in sled pulling, it's not all about making big power. Good rule of thumb is get your setup ironed out before you try to add a ton of power. Another thing I try to do is only change 1 thing at a time. That way you know what helps and what doesn't.
