The maf sensor was deleted when I got the truck (remote mount turbo set up) seems to very finicky getting it to spool off the line, I have read good and bad things about deleting them. Does anyone have first hand knowledge about this? 2004 lly

    I finally got to make my first pull on the weekend with my new set up. Well long story short my stock lmm aluminum drive shaft did not like 940hp going through it lol.
