What can one expect from a tune alone?

I'm just curious about gains I should be seeing going for a tune only (93 octane, bone stock with K&N intake, and flowmaster mufflers). My tuner will be using EFI live and a dyno dynamics dyno.

There is a vararam for sale here. I thought I saw a ported intake as well. Throw those two in there as well and you could pick up about 40rwp depending on the factory tune.

Is it really worth the money between a k&n over a vararam? and if I was going to do a ported intake, I'd just do it myself. Thanks for the idea though, it just might be something to do when I eventually get a cam for it......since the intake has to come off anyway, right?

Yes, there is proven data that can be found on here that the OTRCAI is the best hands down.

Over The Radiator Cold Air Intake. It is the best type of cold air intake you can buy for our cars. Yes it is well worth it no matter which one you buy the Vararam, Svede, or Duspeed. They all work about the same but will be hands down better than those crappy K&N's.

No, a cam swap does not require removal of the intake manifold.

If you are an auto, it will feel like a whole new car with a tune as they will adjust your trans like shift points and line pressure.

To change lifters, you not only need to remove the intake manifold, but you also have to pull the heads off.

Oh, trust me I will be. This is one of the reasons i'm still driving it daily. The headache of choosing a cam has to be done first. I will be doing it myself, so I must be prepared. Just the little knowledge I do have about small blocks, would prompt me to remove the valve covers, intake, front cover, rockers, pushrods, then lifters.

You can change a LS cam without pulling the heads and lifters. There are a couple of different ways to lock the lifters up to allow a cam change. This link describes how it's done (see below). But, if you want to physically remove or replace the lifters, it requires the heads to be removed.
