Over boosting with new BOV
I just installed the Tial QRJ in my car and It's currently hitting 30lbs of boost. the most the stock bov boosted was 28 pounds but it usually stayed around 27 since that's what I had it tuned for. Any idea why it's doing this? The car also backfires here and there

Staying this way? You could window your block, pending where that extra boost/torque is applied on the power curve. You could be fine. A lot of factors are thrown into it. But your best bet is to have it tuned correctly for all parts on your car. If you were just recently tuned, your tuner may be able to throw you a revised map for free, or a low extra cost. I'd personally not risk it and have it done correctly.

Your old BPV could have been leaking, thus the new one is holding the boost correctly (or stiffer spring, as e_kobz stated).

Would it make a difference if I reset my ecu by taking the battery off?

The car is brand new so it's not leaking. Today it hit 28psi so it's not that bad. It only spikes when I go full throttle and shift around 4krpm. The most I've seen it was 31psi. I may take it off and just reinstall it when I go full bolt ons and obviously re tune it then.

I swapped out my factory BPV for the Synapse DV (35k miles), and got boost spikes to about 31-32 psi. Needless to say the stock BPV was leaking. That being said, the car went crazy with CELs. ECU doesn't like to see the boost spikes (over 31? not sure exactly), so it set off my Traction Control, AWD control and CEL.
