They should have put a 25* limiter in it. Most guys are going with 0* or 4* max limiters with cams now. The spring pressure used with aftermarket cams overcomes the phaser sometimes and causes camshaft retarding against commanded. Who ever tuned your car should have done away with the driving retard and set up the WOT retard as GM prescribes for that cam. I guess you will be fine. Consider that the GM cam has 41* more exhaust duration than the stock cam. I would have to run some math to tell you how much later it closes. Not sure if the stock phaser retard + the extra duration will cause issues. I am assuming it hasn't so far.
