I was wondering if it would be worth my money taking my motor to the shop for installing aftermarket crower stage 3 camshaft and aem camgears for my motor? Would it be a good upgrade for the motor. I also install an skunk 2 intake manifold to my motor and was also wondering if i should go get it tuned with all the upgrades parts? If anyone have any thoughts of what i should do for the best upgrade, it would be thankful of you to let me know.
