retuning after ported parts install?
Would adding ported parts (intake mani, exhaust mani, t.b., turbo housing) after a tune affect it a lot? Is it worth getting retuned for just installing those parts? Thinking about getting some parts ported but wondering if a retune after is necessary.

I would definitely get a tune, the ported parts are going to allow you to flow more air which in turn will lean your afr out. By how much its tough to say, but better to be safe than sorry. Also you won't be able take full advantage of the porting without a tune, as the above person said.

I got a before and after dyno run while I was putting on my ported and coated exhaust mani and noticed that boost held on a significant amout longer. I would get a tune as said before you don't want to be running lean...
