Like I said, I can see 18psi maybe with some E85 thrown in, but pump gas-that sounds a bit iffy.
But I am sure it has been done as you say. My other friend who went aggressive on his N54 fried his turbos lol. Luckily our mutual friend is a tech and used his CPO to replace them for free after taking the car back to stock before bringing it in. Replaced his trans for him under CPO too, about $18k all together done for $0. It is good to have the right friends
