if i were to say by a set of aftermarket cams like 260's etc.. cause i know cat cams makes them supposedly and some other companies like shark racing how do these react to the beta for driveabiltiy? I always thought on our car if you drop those in the car and dont tune the car it will run like shit and how do you even tune our car with cams like that cause I thought our car has crazy timing with the chain thing running around. etc.. maybe some more info on how to tune with these or if i can just put them in and go from there and if i were to run nitrous with them any problems?
