Throttle body
What are the differences in the LT1 and LT4 throttle bodies? Can the OEM Z06 throttle body be installed on the LT1 and if so does it require a tune? Are there any benefits?

I agree the stock is 87 mm the zr1 is 95mm unless you are going to a blower set up don't mess with it on just a bigger T.B. on the car at all. Robert

if its off a z06 its just better because it came off a z06 
but seriously at the min you want a ported 87mm tb, no tune required.
the ported stock size i put on from soler did help with my low end drivability which is what i wanted.

I installed a Katech 95mm TB on my 2014 Z51 that's modified with a Vortec supercharger, what I noticed right away was a bit quicker response at the gas pedal, nothing drastic but a seat of the pants feeling, no tune needed.
