What is the easiest way to get 450whp-500whp from the B58? And is it even possible with the stock turbo? Who would you recommend for a custom MHD tune? I'm currently leaning toward Wedge Performance as they are the only ones I know of that will tune the B58 for MHD.

My current mods are VRSF 4.5" Catless DP, Remus Axleback (just ordered), and having an exhaust shop make me a custom midpipe.

I'm on MHD E30 Stage 2 currently.

How much power is e30 stage 2? And meth should get you to 450 plus easily

470hp at the crank.

It seems we'll be able to reach that with e85. most stage 2 dynos are around 420whp. e85 gives you another 40-50hp.

idk about MHD, but BM3 has a couple tuners doing custom e85 tunes.

This is the max power i seen on stock turbo with no meth and down-pipe so far.....

No flash tune has achieved these numbers with the stock down-pipe. With meth it should easily be a 500whp car if tuned correctly through the JB4.

I say stay under 500hp. I'm only at 420hp with bm3 tune and my stock turbo is spooling like crazy.

Define "spooling like crazy". Are you worried about # psi your turbo is making, IATs, manifold pressure...?

BM3 has achieved these. But i'm with MHD, i'm guessing i'll just need to get it custom tuned.

Running 456whp/470tq with stock turbo on a stage 2 tune and meth with e85/91 blend. The tuner said we can probably 475-500 eventually but we’re already almost maxed out at 22.8psi

What tuner? And if you don't mind could I possibly see some of the logs? I'm curious.

I don’t have the logs but the tune was done by Alex at mission performance running their stage 2.5 flash with stage 1 trans flash. I mix 3.5 gal of e85 with 91 and run a 50/50 meth blend via the bms meth kit with an aftermarket HPC meth controller

Gotcha, solid numbers man. Have you taken it to the track?
