boost problems

09 ss/tc. i got a dynojet tune and a electronic boost controller. when ever i build boost over 18lbs itll hold for a few seconds then drop to 0, and wont build until i turn the car off/on. then it says service esc.
has anyone else had this problem? its really starting to get annoying

Sounds like the boost tables in your tune aren't set up for the boost controller. Remove that crap.
