The tune still isn’t done, but, it is the current state of where we are at. There is still a problem with the knock pulling timing, so the timing and boost are set low for now.

TL,DR: 456 WHP, and 518 ft*lbs with just 21 psi & 9 degrees of timing!

Stage 2.5 Setup:
– FBO 2011 BMW 335i manual
– SteamSpeed STX 78R BB Turbo
– Single port meth
– Only 21 psi, 9 degrees of timing
Result:
– 456 whp, 518 ft*lbs torque
Keep me posted on the tune and result. Could it be fuel related? I really like the idea of a BB turbo for my upgrade.
