I personally don't think that the upgrade is worth the price, I just pulled a lightning intake up and it costs about $200, you get most of that performance with just the gotts mod, but with a different TB then yes it would help, but I am not sure how much actual performance you would see for the price you would spend on the upgrades... but that is just my opinion.
If it is worth it to you, do that, and the UDP's, and you should get some more power, but I would be surprised if 40hp more made it to the wheels
