I've seen some people talking about having ported TB's on there LS1's. Can you do this for an LT1 and is it worth it? Also, what is the deal with a ported MAF? I would think that would make your car run bad and wouldn't do anything...I have a 94 Z with LT headers, Matching Y-pipe and a CAI. I can't really think of any more little mods I can do, until I save up for the converter.

 

Ported TB usually= more hp 7-10 at the wheels and better throttle response when done right. Ported MAf usually= headaches, sometimes peeps have no problems though

 

Unless you're making big power and are getting/have a tune, dont port the MAF. My buddy ported his on his 98 WS6 and had some drivability issues. His dad is a EE at Delphi and said it wasnt a good idea.
