Any cam you get, you will need to get a retune. If you dont you will lose a good bit of power and the car will run very rough. You will get a bunch of "I like this cam" so take it all with a grain of salt. I love my 228r cam from Texas Speed as it is very reliable and streetable. Others will say they like their larger cams. Best advice is to hear other goats with various setups either on youtube or in person.
