Dyno tuning by RWTD? I am installing pacesetters with the tsp catted y and want to get the car dyno tuned so I don't ruin my cats (the whole reason why I am changing my exhaust after the stock ones went bad). RWTD said they use HP tuners but that I would need a rear O2 bung installed after the cats so they could tune my car. I didn't know this and was wondering if that was what everyone else has done to their Y-pipe when they get it tuned. Also, would the sensor need to go in the I-pipe, or just after one of the cats?

First off, wideband readings are more accurate in front of the cats...not after. If they don't know how to tune the car using the existing bungs in the headers, I say go somewhere else. I wouldn't want an extra bung in my exhaust. That's just one more potential spot for a leak. It's a little hard to believe they're telling you this...especially with the number of cars they have tuned.
