shoot guess i should have done that too.. had some ping after putting a 20/22r together. tried playing with an adjustable timing gear.. didn't make a bunch of difference.. finally put in a fatter idle jet in in the weber and got rid of the ping. yeah it likes the $$gas better but i run regular. 18 mpg at 65mph. 4.56 dif 265x70 16's.. i average 16-17 mpg.. at 5500-6000rpm I'm sure it's only getting 10 mpg. my motor well diesel if i come in after a hard run and shut it off to soon. anyone ever try water injection?
