No tune is needed, however, a tune will help achieve your mods full potential. Your car should run just fine/better now. Haven't heard any complaints about a bogging problem. You should be really pleased with the quality product you just purchased.
The Cool-Flo does not require an ECU program at all. If your car is bogging, there is an issue with the car or the installation.
Do you have any fellow jetters who live in your region? Maybe someone can have a look if you aren't able to figure out what it up.

everything is complete on the FSwerks intake and from what i have seen on the 08+ models there is no drilling required. that may have been where you ran into a problem with the other intake becuase if there was any air leaking at the point you would have a vac leak and could cause the issues you described. i had a k&n on my 07 and never had an issue save for a lean code randomly one day

yea thats what i was thinking but the drill hole was perfect and the little rubber piece you had to put in there was tight really tight but idk does not matter nomore already sold it basically got my money back anyway
Hi, would I need an ecu tune to get the fswerks cai if I have the cfm throttle body on a 2.0 duratec? I think fswerks tried to call me about that but I was busy at the time 
BTW the rear stress bar was a little harder to install than I thought, but it's nice!!!

Which bar did you get? The bars are really straight forward you can't mess them up. Just pay attention to the way the stock one comes off and you are good to go
Sorry for going off topic but drilling the holes took longer than I thought. I finally figured out to drill at a slow rpm and use a little oil with a nice cobalt bit. Other than taking forever to drill the holes, it was a pretty easy install.
Also you'll like the way it corners if you autocross
the rear STRESS bar and rear SWAY bar are two completely different things.
SWAY bar is remove & replace.
STRESS bar requires drilling etc.
