FS: LS4 T/B + Spacer + Coupler
I've got a LS4 throttle body from a trailblazer with 10k miles on it. I had it on my car for maybe 150 miles. The spacer plate was made by my father by tracing the throttle body. It is only 3/8 of an inch thick aluminum. I didn't need it any thicker as my meth is tapped through the intake. Coupler is a 3.5 to 3 inch reducer.
Looking to sell it all together for 130+s/h OBO

Bascially just going back to stage 2. I had hoped to get into tuning this car, but i recently bought a house. I have had NO time to really learn how to tune. So I have been selling off all the excess.
The only thing quirky about the bigger T/B that needs to be fine tuned is V/E and idle. First start up and coming to a stop RPM's hang around 1500-2k rpm for like 3-5 seconds. And shifting to second is a bit rough, but its a bit rough on the GM stage 2 tune. Otherwise it was VERY noticable in the upper RPM's when i had it on. The supercharger just screamed soooo much louder. Actually at full throttle shifting into second was normal. Regular daily driving it was kind of annoying.
Had i actually learned tuning or had the money to give someone to tune everything then i probably would not have sold my 60's or be looking to sell this.
