RE: Thinking ahead. TUNING!
you do not go as lean as possible, going lean will raise your egt's and get everything too hot and start hurting things!! (crack manifolds, blow turbo's, put holes in pistons, etc etc.). i'm still not all that familiar with tuning numbers but from what i gather a good Wideband fuel ratio number is 11.1

i can lean mine out without knock and get EGT's through the roof when i go to 11.3:1. My car is very picky though, i drove it to work tonight & it runs like ****.
you just have to kinda tune to keep evrything in a safe range. but as lean as poissible is a little far. i could probly turn mine to 12:1 by retarding the timing farther but then the EGT will shoot to melting point extremely fast.
. lose 5 HP and richen it up it will last 50x longer.
For a straigh up drag race car, i wouldnt give two ****s if it knocks the whole way down the track as long as its fast.
