0299 is something I used to get with a 66mm turbo.
You will need a programmer to clear the code or stay in limp mode for next to forever.

Boost fooler don't have anything to do with 0299.

Do the electronic wastegate foolers go bad mine did it twice this weekend, the first time i cleared the code twice before it would stay off. the second time i cleared 3 times for the code to stay off.

i have one of my 06's throwing the p0299 code it started after i let ats talk me into a 3000 turbo and dual cp3, neither one helped my mileage and ats will not respond , i was towing most of the night when it happened once and i was at 18lb average boost for about five continuous hours at the time of failure. with about 1500 miles between failures and no help from ats it is going to be hard to track and like you it does it at bad times pulling a trailer i have to pull off the road and reset with the jr to continue
