After installing the GReddy BCC. My car was dynoed and everything went well. When I took the car up to high speeds on the throughway's in 5th and 6th gear. I am still getting boost cut when I get on the throttle. Right when I start to make boost and start accelerating it gets cut right off. I thought the BCC was supposed to eliminate that!

Could it have been installed wrong? There were no problems on the dyno.

I have the same problem... I talked to Titan motorsports and they said to verify your output voltage. it should be 4.3 volts. I have not checked mine... not had the time. My fuel cut seemed to happen , 5th gear-85mph. It does it like clock work. If I let off the boost then accelerate slowly I do not have that problem.. Keep me posted if you find out what the problem is for sure.
