Recently installed a 18 Manifold with lockouts and had it retuned by Lund on 93 and E85. Car felt really strong after adding the manifold with the stock headers. Not too long after I added the manifold, I had a set of TSP catless headers installed. After the headers the car feels a lot slower to me and even my girlfriend. Doesn't seem to pull hard. Car feels like it has no torque and takes forever to rev all the way up to 7500. I had Lund look at a log after the headers to make sure I didn't need a revision and they confirmed everything looked good. Car is running 30-31 degrees of timing and fueling is spot on. I'm planning on getting it dyno'd with the new setup to see if it's making the power it should. I couldn't find anything out there from anyone saying headers caused them to lose power. Any idea of what could be going on? I've read that using O2 extensions could cause some issues but I've driven the car over 200 miles and haven't had a check engine light come on. Also TSP catless headers don't have an O2 bung for the rear O2 sensors but that shouldn't matter since they're turned off anyways. So they didn't even get put back on the car. Any help or ideas would be appreciated. Here's a link to the log I sent Lund via Datazap.
