any body out there tried upgrading to the car intakes? what kind of results have you seen? i've heard some mixed revues some say stock lq9 is best and i read some dyno results on supposedly stock engine with stock tb and ls6 intake with 1.65 headers and cats with gains of like 60 hp and 50 lb/ft essencialy surpasing the ls2 with 411hp 433lb/ft . which asides from a few pounds is essentialy the same engine only real difference is larger chambers in head allowing for bigger valves and iron block. that just sounds too easy tho?
