I originally had my truck tuned to go with the 3.33 pulley. Ive since gone down to a 3.12, but Im seeing a quite a bit of slip. When I went to the smaller pulley I also added an alky system, headers, and now a cam. Im spraying with a 675ml nozzle that comes on a 3# and full on at 8#. Is there any way for me to check (rough narrowband 02 signal) that Im not running lean? Im going to get a wideband in the near future, but would like to know if Im at least alright. Im using HPtuners. As long as Im not seeing any KR am I somewhat safe given the amount of alky Im spraying? Timing is only 14*, I havent raised it since the initial 3.33 tune.
