We're doing them now, though ironically I haven't played with a 4Runner yet after we've done the BST on them. I'll try and get my hands on one post BST and see if it's as bad as the Corollas. Basically from other people I have talked to that have dealt with the BST, its pretty much the same "kill the engine for a few seconds after you release the brake pedal" in all the vehicles. That's where I am concerned it could cause issues, because IF a customer rode the brakes and/or tried to accelerate and push the brake y accident activating the BST function, then the vehicle would not be able to effectively accelerate for a good few seconds. Thus, potentially a person behind them might not know this and ram into their backside assuming they were able to accelerate properly.
You're welcome to bring it over, but I probably won't be the one doing the BST (not that its difficult, its just an update, its just "gravy" work that the more senior techs typically get dibs on.) But personally I wouldn't bother getting it done, much in the same way I declined the pedal chop 90L recall (I was going to get a new accelerator, but the new ones are made shorter :crybaby: )
