Yeppers. I don't remember the nozzle size. All I know is...no meth and no nitrous @ WOT it's pretty much 11.6ish AFR. With meth on and no nitrous it's 10.5ish AFR. That run was 10.9 AFR for the most part. A couple 11.0's in the 2/3 shift. Looks like nitrous is leaning it out by .5 AFR. Ofcourse the meth probably skews that.
IAT's not really dropping with nitrous and methanol is another big pointer in my mind that the IAT isn't reading true air temp. It's heat soaked and reading aluminum temps. There is now way in hell that those two adders don't cool the charge down.

Ah the guess work with methanol and nitrous. My tuning goes something like.... did I get anywhere above 11.8 AFR through that run. Nope. Sweet!

yep, precise tuning right there. With lots of meth in there I want to see nothing higher than 11.2.
