Re: Western Off Topic
It's because of the scaling. The AFR is going between 11.7-12 it just looks like more of a swing than what it is. Don't forget the N54 is DI so it is safe to run slightly leaner than EFI. Peak boost on that run was ~17.5psi.
I've tried using the VD to plot a dyno run but it always seems to read low. The car made 330rwhp/380rwtq on a dynocom chassis dyno. Now it's running more boost(with less taper up top) and more timing and according to VD it makes about 320hp/340tq. The normal dynojet numbers for my mods is around 370hp/400tq.

The settings must not be correct for the VDR. I've tested an evo back to back from dynojet to the VDR and it was within 3hp/3tq. Be sure the gearing is correct(I had to make some custom files for VDR as some of the gearing was incorrect), and that you have the weights put in there properly.
Also, tire size, plays a big role.

I understand the DI, but running almost 12's on pump kinda worries me for long term use. You will not loose any discernable amount of power by fattening it up a half point, but gain a lot better safety margin. Either way I guess, personal preference.
