There's drain holes all through the hood. The stock ones actually aren't even water tight so I'm sure water already gets in under them, they are just sealed with a little porous foam.
I feel like one of those times where I'm standing in a line and the other line is moving faster and I keep staying in my line. I want to get flex fuel for JB4 but I keep thinking as soon as I do they will get an unlock for new ecu.
Yeah - honestly you could probably just put it to map 0 and they wouldn't know lol. But shouldn't have any auto flags. They could in theory see the boost numbers going higher I think but I doubt they'd ever see that.
Honestly wouldn't be surprised if you made a good bit more power with EWG. I didn't try mine without it but from what I read it's a pretty big difference because of overboost prevention.
