so i was running the TXS stealth back catted of course (4in-3in-2.5in) and have always run 11psi, i just swapped to a full 3in angled catless tb and the gauge is reading 14-15psi, she feels way more responsive and ready to pounce, no lag feel like my old tb....is this common? I know the freeing up by catless helps but never heard of more boost. Thanks

I would have expected boost to stay the same or drop off a bit. Less backpressure on the wastegate means it may crack open. Maybe your old exhaust setup wasn't as restrictive as you thought...

yeah, its seems all fingers are pointing to boost creep, my creep is well under the danger area so i guess i am gonna run with it until can get a fix, just lay of the throttle a bit, also i am loking to get a different catback, this one is a bit loud
