So are the CDC SHAKER ram air kits good for any horsepower? Are the cold air kits better or are they both worthless? Do you need a reprogram with a SHAKER?
the CAI's do require a retune for most and my ram air hood didn't line up with my CAI so it had to be "adjusted"
I really don't know how much the ram air is worth but once i got the CAI sealed up to the outlet on the hood i did pickup about 3 mph in the 1/4mile. I've data logged IAT's and you can see when the ram air becomes effective. the temps drop about 20-30 degrees by the time you reach 40mph.
the one thing about the ram air hoods or at least mine was it put a lot of pressure under the hood making it shake and dance from around from 70mph -up. it was downright scary at 100mph so i put some hood pins in for peace of mind.
