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  |
You're right, that's why I said 'appropriate fueling'. Map 2 of the JB4 for the N55 it hits 14 psi and it's for use with 93 octane and down pipes. Map 7 hits 18.5 psi but requires race fuel or a mix of E85 of 50% with 93 octane.
One could argue that in many places E85 is pump fuel I guess, but I see your point, 93 octane is it not, more like go go juice.
