Agree with Darell. Try not to do down shifting while under boost. Though it feels awesome, it's really bad for the 545rfe transmission. Something to do with the 3rd gear clutches stuff. The fact of the matter. The 545rfe trans isn't a strong trans. But, when treated correctly and built stronger. It can hold up in boosted situations. I'm sure you've heard all about this stuff already.
Boost is soooo addicting........ Happy Boosting.
