What tune up would you rather have?
LOLOL All a Holley knows, idle, or WFO (wide---freakin--open)
That used to be my opinion also, but not anymore.
I have this Holley Street Avenger from a big block motor modified to run on my 5.9 and it's a sweetheart now throughout the range.
I re calibrated the idle and high speed air bleeds and everything.
Which reminds me, I could drop a little on the secondary jetting as WOT is in the mid to high 10's on the AFR.
I'd like it to be in the mid 12's at my elevation, and then in the 13's or so when I go to Phoenix at a couple thousand feet lower elevation.
Until this carb I was stuck on the Edelbrock's but not any more. :D
I doubt I would ever go back to an Edelbrock again.
