Default surge help

I have a 01 silverado, that I have put the L92 crate motor, long tube headers, 90mm tb, and a comp cam the specs are 222/224 566/568 112lsa.... im using the lingenfelter 54 to 24 reluctor converter....a fully built tranny with a 2800 stall...


the truck as is, will start and surge/swing from 500-1600rpms and when it does this the truck dies....

other times if you give it a little gas and let it "catch" it self the truck will start to idle but with start to swing less from 500-1000....


What cause it to Surge?
