Correct me if Im wrong here but If memory serves me right no where on Vol3 does it state especially on 3 . 02 . 70 P5 that using or not using Packs increases or decreases Compressor stall..... and Pant load was right , if your worrying about stalls then youve got a sick engine that needs a write up lest you want to throw your buddy whos taking over a burton !!
