So who thinks their intakes are messing up their car??

That is exactly what I am going to do. Well, I have determined that an intake is not that much of a benefit. With the K&N drop in and no snorkel my LTFT were -6.2. Once I recalibrated the MAF the car pulls harder than it ever has. I leaned the A/F out a touch and am running a ton of timing with no knock at all on repeated hard pulls. I did 60-100 mph last night in 5 seconds flat which is a full second faster than it used to take (really fast considering it takes almost a full second for the throttle to open). It went from 65-100 in 4 seconds. 
What's the part number for the K&N? Short of doing an airbox mod, would you suggest snorkel or no snorkel for max flow when coupled with the K&N? (Getting my pre-tune setup finalized)

LOL hey while I am here what is the cheapest catless downpipe for the LNF???
Is it ZZP for 239??? That **** is pricey for a Downpipe. I thought they used to have them for 189.

If its stainless then $239 is a good price. I seriously doubt the one for $189 was made out of anything other than regular aluminumized steel

K&N drop-in is part #33-2311; picked mine up for about $45.
Props to all the tooners for their efforts. Kind of sheds light on why GM is still working on the Stage II intake. Hopefully the airbox mods will work well with the Stage I.

I logged this on the way home tonight, ZZP snorkeless airbox mod, K&N drop in.
29.1 VE Airflow at the top of 2nd. Got the LTFT's and the top end STFT's pretty close now. Still seeing some KR at lower RPM, high loads.
