well today was a wierd experience lol..I pulled a uhaul to school for the gf. it was the biggest enclosed one they have, so it weights like 1500 unloaded..had 2 couches, a fridge, chairs, bed etc in it..prolly 3k at least..i pulled that 175 miles to school going 70 and then drove the 175 miles home without it, for 350 miles total and then the gas light came on..my MAX ever was 355 miles and that was cruising interstate for the entire time going 65..so id say my little intake mod/cleaning the maf and filter helped..its just a bit over 17 mpg and that was with pulling that uhaul..
also on the way home i got rolled for tint, tinted tails, clear turns in front, cracked windshield..fix it tickets..pain in the ass
