Hello USA7s. I finally purchased a Brunton Stalker XL powered by an LS3. I have lusted after a LS3 Super Stalker for quite some time. The car is magnificent. The previous owner took excellent care of the car. He was the second owner. Unfortunately he had no documentation such as parts lists, wiring diagrams, general info, et cetera. He did identify what all the dash switches are except for one mystery three position switch he had no clue what it is for and operating it reveals nothing about its function. Being an engineer and ex-racer, I'd like to compile as much info as possible about the car. If it has a Brunton serial number, I have not found it nor know where to look. The car has a funky dual cat (four O2 sensors) exhaust system that goes under the car and exits at the rear. I would like to replace this with the standard side pipes exhaust with just (2) O2 sensors. He did not know what LS3 version the engine was but I suspect it is a 430 HP version. Anyone know what the header/muffler/ turnout part numbers are? If I convert the car to the standard side pipe exhaust system with (2) O2 sensors I suspect the ECU will need re-calibration and if so does anyone know who can do this? I'd like to get to know all fellow LS3 powered Stalker owners, especially those in southwest Florida.
