airfoil, hypertech are a waste of money, others are good though but you really wont gain much hp from any of them, maybe 5hp for the open lid and K&N

I would say you definitely increased some power. Not sure how much - but the t/b bypass
lower thermostat
flowmasters
K and N
Open Lid

All helped you, get more (volume), cooler, air in and exited a little better. You didnt pick up 100hp or anything, maybe like 10 to 15??? (Might be generous). Seriously, I put Corsa's on mine, but I dont think I picked up anything. I gotta get my car dynoed just so I know what I have....

But you set the stage for your future mods....intake, heads, cam, headers....

You probably picked up a bit but if I were to do it I'd drop the airfoil, pulleys, & hypertech (buy a lower fan switch instead - get a chip when you finally really need it) from the list and put the money for those items towards some more airflow mods (runners, intake or more exhaust stuff).
