Looks good, AFR is a bit lean though.

Isn't there a law about having to do headers before heads/cam. If you put some LT's on there it would give you a nice jump. You already had the manifolds off to do the swap... and you bolted them back up.

 

nice numbers, but way to lean

why no headers ? emissions ?

 

Holy **** that things lean at the top! Too lean the whole way but real bad at the top.

 

I agree with needing headers. Just the price for the cam, 918's, and LS6 intake, and 243's I couldn't pass on. They were a steal of a price. Besides I want Kook headers. No point in buying other headers I'm just gonna sell later.

 

Too many dyno operators will tune that lean to post up a number for bragging rights. I'd never run a car that lean on the street and expect any life out of the engine. Setting it to run at 12.5-12.7:1 may cost you some dyno numbers but the engine will not be a ticking bomb. Besides, how often do you drive around - on the dyno.

 

Won't his AFR read more lean than it actually is because of the cats? Assuming the wideband is behind them.

 

Gotta say I'm a little lost when it comes to A/F. The car is untuned although. Thinking of going with #30 injectors to compensate for the fuel loss up top. What do you guys think?
