Ok so I did the tbss swap with a nnbs throttle body, I'm finally getting it tuned an my tuner says it is showing 100% at 3/4 throttle an when you do floor it the comp looses connection to the tps, truck goes crazy an into limp mode. It's even showing 13% throttle at idle or the truck off. I have the xlink, any thoughts? Truck is my dd.

 

Is the pink wires on the x-link still together or cut?

 

There still together.

 

Which TB or you using?

 

I was told it was a nnbs truck tb.

 

Could you post a pic? Some TB require the pink wires to be cut & some not. When I installed my 90mm tb I miss read the direction & cut the pink wires & it did the same thing that yours is doing

 

Link below. Should I just cut the pink wire an see if it works? It's delaying me getting it back an it's my dd.

 

90mm L92 DBW Throttle Body - LS1TECH

 

the throttle body could be bad 05gmcsierra had a similar problem ,

 

Does it look like this


If so it shouldn't need pink wires cut. It could just be a bad tps in the tb.
