Anyone notice a significant delta in the boost readout from the dash versus either gauge or ebc? I'm not expecting the 2 to be dead nuts, but they are quite a ways off. See below...
For reference, I'm running a StageII Procharger kit pulleyed @ ~15psi. Since I'm running pump (91), I added a GFB G-Force III electronic boost controller and a Tial MVR wastegate w/5.8psi spring.
The dash reads somewhere north of 8psi (I believe I saw 8.9psi at peak) while the GFB peaks between 3.5psi - 3.9psi. As a result, I haven't pumped the duty cycle too much (10%-30%) thus far as I'd like to definitively eliminate the possibility of overboosting if the ebc is incorrect.
Vacuum seems to be much closer between the two but I can't get as granular there since the GFB only reads whole numbers (inHg).
Based on the spring pressure, I'm more inclined to believe the dash readout at this point.
Thoughts?
