I bet you put down 315-320rwhp and 340rwtq.....Yes, get a CAI...they are worth some power. I have the K&N on my mach and I think the performance is great, but they seem to cause stalling issues. For some reason when you come to a hard stop the car wants to stall. LOTS of mach owners have complained about this. Not sure why it happens every now and again, but do a search on the mach 1 registry forums and you'll find several threads discussing this issue. JLT makes some nice stuff.
Yes, get a tune immediately after having your stuff installed. I added a CAI, mid pipe, and cat back to my car and took it directly to the dyno and good thing I did because my A/F ratio was almost 14.1 if I remember right. You can get away with adding two components that bring it more air (catback, and CAI), but after that your A/F will go way wacky. Mach engines are pretty sensitive
