Cool, i am in contact with Todd at wolf creek. Is there anyway i can tell what jets i have in it right now?
Does anyone have a link to the manual? I have never changed jets and such, is it pretty simple?
Thanks

Jet sizes are stamped on the top of them. If you can't read them, get a magnifying glass. Some tuners grind the #s off to hide thier settings. Todd sells a photocopy manual or you can pic on up off eBay on cd.
Mikunis are simple compared to Holleys and Nikkis.

Depending on which size of jets you order, I might be interested in the leftovers that you don't use. PM me with the sizes when you're done tuning tuning. If you can, get your hands on a wideband when you tune, it will make a big difference dialing in the afrs Don't be too concerned about afrs at idle, they tend to run in the 8.5-10 range. During hard acceleration, 10.5-12.5, steady state cruise near 14. Hardest part can be getting rid of the bog when you begin to accelerate.
If at all possible, dyno tuning will yield the best results, but that can get pricey.
