I cant help to comment. All sv6 llt owners should join the threads in usa regarding the camaro 5th gen v6 and bowtie v6 forums. Guys are getting almost 400 hp on stock internals N/A with minor mods and a complete ecu overhaul. These motors are dumbed down because they out perfomed the ls1 in general motors testing. There is alot of power waiting to be realeased from this great little motor. Do some research on the llt and lfx.
