Surging and timing pull under wot

[Blue95sil]

Need a little assistance if anyone can help. i've got my truck to idle good and it drives fair but on a cold start it surges and might cut off, it sometimes surges when i'm driving and coming up to a stop. on WOT it pulls timing and will put timing back in after a few seconds. i'm chasing it constantly but i'm apparently missing something or overlooking it. any help is greatly appreciated and credited. Thanks in advance

Start by returning all of your "Abuse Mode" trans tables back to stock, to help with the random timing pulls, and fix your "Startup Idle" tables. Then see where you are after that.
