Anyone running LTs with their canned tune on an L86 truck? Any issues? Was seeing if it would work for a while before I got a dyno tune.

you'd need a custom tune done to get airflow/fueling dialed in correctly.. .you will have the CEL on due to multiple trouble codes thrown, which also need to be disabled via a custom tune..
