Depends how lean.. 14:1 is risky. I've seen dyno pulls cut short when the a/f spikes to 14 or 15:1.
You technically should have it tuned after a LT install.

How do you know its lean? Do you have a wideband? If so, what are the readings?

I agree, if its 14:1 at WOT, then dont run it.. 14:1 at idle/part throttle on the other hand is fine.

Lean tune due to modifications combined with cold weather intake air is a prescription for disaster. Losing your investment because you were too impatient to tune would be stupid. Once you modify your car you will be lucky if it runs as good as stock without a tune. Why race it knowing it could destroy the engine and that it will not perform anywhere close to its true potential??????
