need help with overboost!!

[mikeyz]

i just go finished putting an engine in my truck. it runs great, but every once in a while it will overboost cut out then run fine and the check engine light will come on for a few seconds. i check the code and it is 31 turbo overboost. i never had this problem before the engine went but it also sat for 2 years so maybe something went bad. please if any body can help write back or call me on my cell at 267-242-3042. thanks, mike

Weather can effect this, deleting the cat on a stock turbo'd truck or cracked/leaking vacuum lines..either way try adjusting the wastegate rod a turn or two.. and check for vac leaks
