Here's the results after the Brian's RPM Switch mod...As you can see, the AFR curve is flat as EFI. This is running 1 bar and VP MS 109 and it is a little lean over 5500. Which I plan not going over anyways for the street and even if I do, it'll be a sec or two max. Seeing that max HP is around 5400, anything over that is wasted. If I bring it back down to .8 bar, I should not have any problems.
The original AFR curve was way below 10 (off the scale of the WB sensor) and caused a lot of rich stumbling as you can see from the torque curve. Now that it's 12ish, the TQ curve has smoothed out dramatically.
I gained 30-40 RWTQ through out the RPM range! So this puts it around 480HP and 475 ft-lbs*! * 15% drivetrain loss.
