Default STi running rough after switching intake

i just switched from my aps 65mm cold air intake to a short ram intake. i reset my ecu and just drove it, now my car is running fine, but when im in 1st thru 3rd gears in low rpm and hit WOT it has a strong hesitation then just kicks in. no its not turbo lag lol its real rough at first...do i need to re tune? no accessport, its open source tuned. do you think the ecu just needs to get used to the short ram? my MAF is installed correctly and theres no leaks. thanks for your help!
