hey guys, need a little help with my setup. i bought this truck last year for dirt cheap and have been trying to sort out all of its issues. its an 02 silverado ECSB 2wd with a 5.3 and a procharger D1SC making 12psi. the motor has been rebuilt with stock crank and rods with ARP bolts and has a set of custom wiesco pistons that dropped compression down to 8.5:1.still has stock heads, cam,intake and throttle body. all this was done by previous owner. the truck made 365rwhp through LT and a horrible 2.25inch exhaust. since ive owned it i put in a racetronix fuel system and hotwire, 60lb injectors, FLT lvl7 4l65e, yank pt3200, alky control meth kit and 3inch true duals with magnaflow xpipe and mufflers. what do think ill see on the dyno since my changes my goal for this truck is to run mid 12s id like to see about 450rwhp. Is this achievable with my current setup if not what should I change. Thanks

 

Should make 450 pretty easily
