i had a supercharged setup do the same thing on startup, it turns out my MAF was biased and was reporting incorrect airflow rates to the pcm, replaced the maf and issues were fixed, perhaps you should try swapping out the maf and retesting.
Hi jwog666,
The MAF is new, but thanks for your reply.
Kyle, there are no aftermarket parts on the car. Just the Roush kit.
