car dies after giving throttle

[240doubledrive]

I need a suggestion on what to do. I have an sr20 in my s13 and I had an safc before. I upgraded the turbo and went with the power fc. The safc had the option for the bov to be vented into the air and the car wouldn't die after it goes off. Now I got the power fc and it wont idle after throttle. It pulls great and runs fine its just I have to give it a little throttle to keep it alive after I get off the gas from high rpms. Any suggestions?

could it be from my bov? Its a hks ssqv and when I got it it did a nice tsss sound. Now it does the tsss, tsss, tsss, tsss.

If it is venting to the atmosphere that can be part of the problem resulting in the car dying. If it makes fluttering noises then it is more than likely overtightened and will cause the turbo to go out sooner than later.

Fluttering = Compressor Surge

Also do you have the Commander with the Power FC? Or just the Power FC. If just the PFC did you get a map with the idle control set for th right RPM. We kicked my friends idle up some when he got his cams and bov.

pfc with commander. We kind of solved this problem on the dyno. We maxed out the injectors at idle to keep it alive. I'm going to move the maf to my cold side and see if that does anything. My bov isn't tight at all because I had the screw completely out when it started fluttering.
