Oh that's not bad at all. Do you know what the numbers would be without E85?
About 350-360 whp/410 torque on 93

380-400 whp/450 torque on e85.

2014 335i and 435is make about 20 whp more
That's actually pretty good. I was expecting low 300s.. But pleasantly surprised. All I really wanted was 400whp anyways so that answers that.

If you're running a stock Cobb map and get pro tuned could you see numbers above 380-400?

Thanks for the replies guys
Im running 301whp / 365tq on just a cobb protune / secondary cat removal / k&n drop in filter & Alpina TCU Flash..much bigger gains w/ FBO / meth obviously
I'll probably end up just running the Cobb tune first and then slowly working my way up to FBO with a protune. Now I'm much more open to N55s though. At first I strictly just wanted an N54. We'll see what cars come up for sale though
