Jealousy has nothing to do with for me. I just stated that it was a LS2 TB in my first post and asked if it ran fine in my second and gave a reason for why I asked. Ive never seen a LS2 calibration run fine on an LS3 or vice-versa. Its always something to investigate when something works for someone and doesnt for alot of other people. Ive also never seen anyone try a 2008 G8 GT TB(assuming thats what it came off of based on the OPs post) on an LS3 car either so that may have something to do with but not sure. Just an idea.
Like Ive told a few that have called me about this thread I didnt mean to kick over an ant bed lol. Just asked a question.

Not really aimed at you Bo white. More to the others that constantly call bs in everything terry post. The car runs and that's the bottom line.

the LS2 will bolt up and work, but it isnt apples to apples.

at WOT, you should be fine because the blade will open 100% either way. Down low is where guys will run into a probem and its a little unsafe.

The calibration of the internals and ECM scaled tables are differant between the two systems. So, yes the blade opens in a differant direction.

The low end driving is what will be effected and could have surging in traffic issue. you might think your pushing down at 40 percent thottle but your unit might be at 30 percent. OR your pushing down 40 and it thinks 75 percent. The LS3 vehicles have differant MAP tables. actually they have mapping tables in HP Tuners and the LS2 vehicles dont.

Id just be VERY careful in traffic with cars in front of you so you dont have to repaint your front bumper from an unexpected surge because your throttle body mechanics are thinking very differant from your foot.

Save your car and buy a ported LS3 throttle body for easy gains and not down side.

I bet there is not much considering they have the same ECM. This is an l76 throttle body.
