whipple 11lbs of boost. engine knock
i have the 10lb pulley on my 5.3 silverado and i was amazed to see the boost guage hit 11psi. it was mostly 10lbs but it hit 11lbs for about 800rpms. i am afraid it has a slight knock at idle but its hard to tell. i did find metal shavings on the oil plug tho:/ anyway looking for a 6.0 now lol any recomendations on what year of 6.0 to look for for an easy swap into a 02 5.3?
