Truck weighed in tonight at 5380 also ran a personal best 15.56 (.1 sec faster) and trap was somewhere around 88 IIRC. I used 3 different formulas which included a combination of (weight,et, and trap). All 3 came out to about 280-285 HP to the ground. Looking around at some others numbers that seems a little inflated. Mods include Volant intake w/ ram air, e-fans, Nelson Tune, OBX Headers, true dual exhaust w/ magnaflow DI/DO muffler.
