Here are a couple quick runs of it going into REP mode with a tune. Thanks

Give me some time,I'm looking at it now.Also check your throttle blade by hand @ WOT the blade should be at a 90 degree angle,See if it goes past that.Mine did,And If I remember I drilled a hole and put a stop set screw in to stop the blade from going past the 90 degree angle.The air being forced in might be trying to flip the blade the other way if it goes past the 90 degree angle.Just a thought.

Did you update efilive? There was a "bug" awhile back that affected the throttle tables.I see in your log that the throttle % is moving around a bit.You might have to go with a cable TB.Boost pressure might be moving the blade around to much.
Just for the heck of it,Try scaling your injector flow rate downward about maybe 25%,You would also have to minus 25% off your VE table also.Do you tune your truck or does somebody else?
I am doing a majority of the tuning. Justin at BBP is helping when I run into problems. He isn't sure why it is happening either. I just tried my LS7 TB back on it, and tripped P2101. I also increased B0120, and that didn't help. DRX is helping too. I will try to update EFI Live to see if that helps. If I knew I could go to a cable I would do that. I'm not sure if I even can go that route. I have searched all over and can not figure out how to do it.
I would really like to connect the wires coming from the TAC module that tells the desired TPS, and the actual TPS off of the TB to eliminate this problem but DRX says it will trigger REP because the signals are too close.

I read your 1st post again.You are using a X-LINK What is it and what does it do and why are you using it.OK never mind,Looked it up,TB adapter.What TB was on the truck before the SC and what pcm are you using.

I am using the factory PCM #12592618 with a COS 3 semi loop SD. Currently I am just running straight SD though. The factory TB is a 78mm (I unfortunately can't put it back on as it is a 3 bolt, and I have to now use a 4 bolt TB). I have two 4bolt TB's. One is 87mm that would come on the newer style trucks, and the other is a 90mm that would come on a new Camaro (LS3/LS7 style).

Have you tried the stock 78mm TB with the factory harness/wiring? I would still update your EFILive.
I can't try the 78mm TB as it is a 3 bolt. The flange is now for a 4 bolt. I had a typo earlier, and fixed it after you posted that.
Well I reduced my blade to 85% hoping that would do the trick, and still got the same problem. I would be happy to go to a cable driven TB if anyone knew how to do it.
