well i just bought a powerdyne supercharger, intercooler, and 42lb injectors. it will be adding to all the mods in my sig.

i got the stock pulley and i was wondering if i will get more or less boost with my ASP pulleys?

from what im told my motor went lean on #7 that is on a NA motor with bolt ons. what should i do to try and prevent this from happening again with my new motor(stock 5.3) and FI. https://www.performancetrucks.net/fo...d.php?t=394676

also how much HP/TQ do you think i will be pushing with the mods in my sig and 8-9 PSI?

thanks

 

run a victor jr intake with your new sc and get a good tune on it....also std guages will help watch out for your new motor....

 

You will need to remove the underdrive pulley.

 

yep, the underdrive pulley slows down all the accessories, not what you want when its turning the pulley you rely on for BOOST! you want it to turn faster, making more boost, which is why companies sell smaller pulleys for their superchargers, to make more boost.
