the p1336 crank position sensor code can and will affect your performance. You are likely off 1 or 2 degrees timing and the pcm can actually keep/retard the tc from performing properly. The pcm will eventually relearn the cps by itself, but at the expense of bad performance and fuel economy. A tech 2 or snap on scan tool can be used to relearn the cps.

Nice..I love working at a shop

 

my brother got his nelson in today and mines on the way. you can feel the shifting and the torque management but we just put it on like an hour ago...Allen from Nelson Perf. says that you can expect more gains as you go. for instance the more the engine learns what new crap is done to it! Very nice soo far tho! Cant wait for mine to come in friday
