untuned lt1
is it a m6 or a4 car?? u def. need to get it tuned if ya ran afr heads and a cc306. it will run like dog doo doo and there will be absolute no low end power. what afr heads or those?? you should be at around 400rwhp with a .30 over motor afr heads and a cc306 with full bolt on car. get it tuned most importantly.
