Looking for a good deal on one let me know what you have.

 

bump....

 

Having issues with the TBSS TB I have. Hoping a car TB will work better and hoping to find one I don't have to go broke to buy.

 

Pardon my ignorance, but whats the difference? The TBSS has the LS2...

 

The truck throttle body is a different design than the car throttle body. The truck one is actually 87mm and the car is 90mm. Not a big difference, but my problem is that apparently the truck style doesn't always play well with the X-harness possibly due to the way it's built. I'm getting a P1516 code at WOT that I believe is due to the TB I have and I'm hoping the car style will fix that.

Dont mean to jack your thread but isnt the only car the ls2 came in was the corvette?

 

No problem. The same TB was in a few different cars including the GTO, G8 and the corvette. The LS7, LS2, L76, LS3, and L98 all use the same car style throttle body.

 

did you tune your truck to work with the throttle body?

 

Other than a small adjustment to help idle learn quicker there really isn't any tuning that needs to be done for operation of the larger TB. The x-link takes care of it.

I have made some additional VE and idle airflow adjustments, but they are minor and are not tied to the P1516 code problem.

I think I'll double check that the TB I have isn't binding up in anyway. Maybe even take it apart and check it out before spending money on the car style.
