......ummm where do you get that information? Lol I dont see anyone on stock turbo making 520whp on stock turbo. Pretty sure that 500+ whp is faster than a stock turbo pushed to the max
But by all means.....do whatcha want your car and all....just dont come back a few months from now and cry about how this platform is weak and trash cause you went ecoboom lol
I have everything you can bolt without replacing the stock turbo. The biggest difference I have had in regards to higher rpm drop offs is the turbosmart wastegate with a 14psi spring. It now holds 25 to 26 psi to redline. Before that it would drop a couple psi in the top end. Now it holds steady.
I've ripped my EBM since day 1. Did several redline pulls and allowed the engine to slow it down. Immediately changed the oil and have hit redline every day since. 34k miles on my 2018.
Doesnt burn oil, valves are clean ect.
I do maintenance religiously. but beat the snot out of her daily...
Water injection shouldn't need a tune like meth does. But then again....water is used for just cooling off the charge temps really, not octane boosting
Theres a FB group called "Let's break some Ecoboosts" and its dedicated to pushing the platform to its absolute limits. No talk about first mods ect....this is balls to the walls discussions.
