Car was recently BPU'd.. 2jzgte USDM car.
mods are..

3" downpipe/3" highflow cat to 2.75" Y-pipe and dual HKS hi-power exhausts
Greddy BCC
HKS SSQV BOV
Greddy Profec B-II boost controller
BLITZ Boost gauge
Colder spark plugs
Running stock side mount intercooler

Car is not boosting past .7 bars at all. With the boost controller on I have problems with boost period.. (boost drops at high rpm.. doesnt pass .7 bar) so i turned it off.. something I noticed.

4th gear WOT at 100mph~ the car HALTS check engine light comes on for 5secs.. then disappears... car is fine.. and i can repeat it again at WOT.. i think this is boost cut.. but my gauge peak boost still reads .7bar.. boost cut should be at 1bar.

I need help trying to find out why my gauge and boost controller only read .7 bars when my car is obviously hitting 1bar boost cut.. (which means my BCC is not installed correctly) After i fix my gauges I can fix my BCC and then see why my boost controller wont boost more)

any ideas?

Fuel Cut probably.. Mine did that at 20psi and I have FCD installed.

Yea thats what i thought also its fuel/boost cut. However both my boost gauge and boost controller show me at .7 peak boost when it happened. Thats still stock -_- how the heck am I hitting 1 bar to reach fuel/boost cut.

I wanna fix the gauges to read correctly before I go back and fix the BCC. If i fix the BCC first ill be boosting 1.5 when it reads 1.2 -_- and thats means KA-BOOM on turbos..

James what boost controller are you using?
