RE: Why don't all intakes require a tune?
well i was the test mule for the afe and id did fine i didnt need a tune and got good numbers. then i added the x and removed the AFE its still in the garage. they mached the maf to the amount of air passing buy it so that it would work within the computers range.

Most XCAL/ C&L combos are tuned specifically for the intake, therefore the tune and gains will be more simply because they complement each other. The price on the combo is between $550 and $650, with the tuner accounting for $400 of the price. My question is how did you save $200 on a K&N since I'm pretty sure they rune around $200 to start with?

The throttle lag is a software issue, not an airflow issue. As for their dyno sheets, there are dealers out there who claim a throttle body spacer makes 20 HP.... meanwhile, several shops have tested them and seen no improvement AT ALL. I seriously doubt a drop in filter makes 7 HP difference. Just my opinion, but shared by many others.
My advice remains the same..... get a CAI and tuner to get the max benefit, and don't waste money on a drop-in. My opinion.

I agree with you though, a drop in filter would most likely do sh**
Sorry if I confused you about the K & N!!!!!

I have the K&N CAI as well ... I notice that the tube starts large ... then decreases in diameter just before the MAF ... then the diamter increases again. I am guessing this design along with the filter increases the amount of air going into the engine but keeps the air speed high enough not to screw up the factory computer settings ...
This is all just a guess ....

I had my car Dyno yesterday and had a GT Muffler installed. My sheet showed a gain of 24. If I choose to add a CAI now should I go back for the retune?
Hoever this is a mute point if I go ahead with the SC

IMO, if you really want to put a CAI on, and are going to eventually get a S/C, go with a CAI that doesn't need a tune. You're cost is just going to increase if you have to have your tunes redone. And then when you get the S/C, you're just going to have to get the tunes redone again. JMO.
