c6 intake and tune question
Hey guys I picked up a 2005 c6 z51 6mt the other day and im looking to get an intake. My question is with my old car (06 mustang gt) I HAD to have a tune with my intake or the car wouldnt run right. I am looking at the slp backing or snake charmer intake and want to know if i have to have a special tune for it or if i can just install it and be good to go.

I would budget for a tune along with whichever system you decide to go with. you will see a large jump in HP/TQ AFTER the tune compared to your first pull with the aftermarket system on the car if it is un-tuned.
Just relaying what I experienced when I did just what you are asking.
Also, I have the Vararam and would buy it again.

alright guys thanks for the advice, I just was worried that it would make me run lean/rich like it did with my stang. Based on your experience with the vararam intake, do you have any numbers you could give me as far as what kind of wheel hp numbers you say before/after? they claim up to 30-40whp in the 1/4 and up to .4 tenths which seems a little much for just an intake, but who knows

Mine ran really lean off idle then overcompensated by going rich Above 4k rpms. But, the intake is not the type to fluff on the dyno like some that like a big fan in front of them.....the Vararam will shine in the 1/4 and real world driving as many have proven if you look at the fastest cars list. Sorry in advance, this reply is from my phone.

The car comes from the factory running pig rich already. Better air cleaners will add to it being lean at cruise and it will run even richer WOT. Contrary to others that say it doesnt hurt it, over time it is bad to run that rich.

So the factory tune will reclaibrate by dumping more fuel at WOT thinking it is running lean. Are the factory tunes set at cruise speeds on the lean side? If the aftermarket air cleaner causes a leaner cruise mixure, would this trigger the Knock sensors and pull timing?

A very important change is made when we add/change these components. Even though the same amount of air may be flowing, the frequency reading out of the MAF to the PCM may change slightly. This is possibly the most important measurement inside the PCM. Everything that happens in the PCM is based on grams of air as measured at the MAF. Getting the MAF right after making a CAI is a critical step in keeping your fuel trims closer to zero, having better drivability at part throttle and hitting the right AFR at wide open throttle. Technically, after making these changes, the MAF, AFR and timing should be recalibrated to maximize the changes.

Not bad at all, just take your time and make sure your system is resting on the front tabs and not in a bind coming through the shroud. I also like how easy it comes out for example when I swapped out my stock intake manifold and throttle body for my ported SPIN MONSTER pieces
(which are AWESOME)!

I can't speak highly enough of the AirAid intake system - their engineering, construction, materials selection, fit and finish are more robust then OEM pieces and they set a new bar in the aftermarket air intake systems - there is no better value or horsepower available from anyone.
Installation is under 30 minutes and when you are done, you have a system that screams performance and yet looks OEM. Every hose connection is "double ribbed" to ensure retention and the air bridge is reinforced to eliminate deflection and preclude filter leaks. AirAid utilizes the factory locating pins to stabilize the unit under cornering loads and comes complete with "winglets" that seal out under hood heat so that evey breath of air is fresh.
You will have zero issues with the AirAid intake system and absolutely no tuning required. The AirAid guys really did their homework - the fuel trims in the stock form are 5-10 points lean and after the AirAid installation you will find the trims are now closer to zero.
Last thing - check out the pricing - it is the lowest in the market and available from hundreds of dealers - I don't endorse any product not fully tested by us and I can assure you - the AirAid will not disappoint you.

so now im hearing good things about the air-raid and slp backwing as well. Tough choice, one thing I just realized about the vararam is that you have to cut the radiator shroud, or buy a precut one. Im not to sure I like the idea of cutting something. And for those of you who use a handheld tuner like the diablo predator, how easy is that to tune the car with lets say an intake and exhaust?
