also what did you do with the vacum line since the tbss has the inline vs truck having the internal? i just got a 08'tbss manifold/rail/injectors/tb and will be doing this swap soon. so far i have gathered:
-drx harness
-try to re-use the truck fuel rail/injectors by drilling new holes on rail or using the tbss ones by splicing in the diffrent style connector.
-cap off fwd vacuum line and delete code/ or get the inline from another tbss.

THA VACUUM LINE YOU ARE REFERRING TO IS FOR THE EVAP SYSTEM. YOU CAN USE AN INLINE SOLENOID FROM A TBSS OR AN F-BODY. I BOUGHT THE OTHER 2 LINES FROM GM AND THEY WERE ABOUT 60 BUCKS. I HAVE A STOCK TBSS INTAKE AND FUEL RAIL AND AM RUNNING 42 LB MARINE INJECTORS. EVERYTHING FITS AND NO LEAKS AT ALL. MY TRUCK IS AN 04 WITH A RETURNLESS FUEL SYSTEM. I ALSO HAVE THE CAR STYLE T-BODY. I WANTED THE TRUCK STYLE MOSTLY FOR LOOKS BUT I COULDN'T GET IT TO WORK CORRECTLY. IT WOULD GO INTO REP MODE AFTER 4500 RPM'S. BOTH THROTTLE BODIES WORKED FINE ON A TBSS BUT ONLY THE CAR ONE WOULD WORK ON MY TRUCK.

AS FAR AS THE SWAP I AM NOT SURE OF ANY GAINS CAUSE I DID THE 6.0 SWAP THEN A WEEK LATER I DID THE INTAKE SWAP. THEN I FOUGHT THE THROTTLE BODY ISSUE FOR A WEEK THEN I HAD IT TUNED.

WHY ARE WE YELLING???
huh???????????????????111111
I think what we're seeing here is a trend that when the efficiency of the intake port is increased, we're actually cutting our own throats because no longer is the truck intake manifold "tuned" to the proper flow range in which the heads and cam are working. Plenum size needs to increase along with intake runner volume to maintain and keep up with the new flow intake. I would have been better off I think had I left the 243 heads alone. Now that I fubared the heads by having them ported I am going to consider porting the truck intake or upgrading to a TBSS intake, whatever is more efficiently priced.

The throttle body with the aluminum housing is stronger than the plastic housing style and works better. As for the REP, as long as you use the most recent X-Link you can tune out any other throttle body problem. It can be made to work properly.

i do have the most recent one. that is how i learned first hand how good there cust service is. we emailed back and forth several times over 2 or 3 days. if you search this forum and the tbss owners forum it is a pretty common issue with any modded 6.0's with the 90mm conversion and dbw.
