Power FC boost discrepancy
Hey guys,
I noticed that the boost numbers on my PFC are a couple psi lower than on my Defi gauge. I read in another thread that this is normal for the PFC but can be fixed.
Does anyone have any info on how to re-calibrate it? Isn't this causing a problem since I'm actually boosting higher than what my ECU is thinking and tuned for?
Suggestions? Comments? Discuss? Candy?

Or you don't have to worry about recalibrating it, I never did, just have to make sure you don't over boost and make sure you are not running lean, don't boost too much if it's not tuned good for any boost above 10-12psi. A wideband is great to have. Search is good.

If you use the calibrated values for the scale/offset, then the PFC will read correct.
But if you have a special tuned PFC for a modded engine, this will cause the rows to be slightly off at high boost and may mess up your tune.
