If you get the right one it should bolt right up. I have heard of some people having to trim a bracket or something. I have a ported and polished one on order now.

I dont expect any performance gains on a mild modded motor with the exception of snappier throttle response.

I dont think you will find anyone with one excluding supercharger guys or heavy mods that said "wow"

I have a patch that I do for the LS2/7 throttle body swap. It will remove the short shifting and pulling idle that you get.

Is this a problem with any etc/tps sensor - as in.. the sample rate is too slow for the 'quicker' ls7 tbody.. Or is it mostly with transient fueling?

Na, the running airflow is a bit differnt. So less % means more CFM and that can make the thing shift up quicker. It can also make it pull going down the road. That part drove me crazy. I don't hear many others complain of it though.

Some just zero out or dramatically lower min airflow above 2k.. I've had a lot of fun tuning that stuff with my cam. heh.. I haven't 0'd out above 2k tho. I can imagine that the coastdown issue would be dependent on coastdown spark & MAP.

Will hook straight up and has a better flow design......look at the 2 when you get the LS7 and you'll know instantly what I am saying!:2cents:

The LS2 And The LS7 Throttle Body Share The Same Part Number, GM PART # 12570790. How Can You Get Better Performance From The Same Part Number. Maybe The Throttle Response Is Slightly Faster Because It New.
