I own a 85 GSL-SE with an 89-T2 engine (88' ECU, 3" exhaust, Bosch Fuel pump, FCD, Stock IC). My car will only boost 5 LBS, and seems to run out of fuel at about 3500 RPM when I floor it. I was wondering if you FC guys are using, or have ever used a Boost Dependent FPR. Do you think this might solve my problem?
Thank's

BTW I also have GSL-SE Secondaries.

All FPR's fitted to every car out there are "boost" dependant. The higher the manifold pressure, (boost or vacuum, doesn't matter), the higher the fuel pressure at the injectors.
The turbo on the 89 engine uses electronic boost control, which won't operate using the 88 ECU, meaning low boost. What makes you think you're running out of fuel? At that low boost and with a decent fuel pump you should have plenty.

EDIT: Wait, just read your second post. Witout control of those larger secondary injectors you're loosing power when they come on at 3800rpm because it's running far too rich. You're not running out of fuel, you have too much. You need a fuel controller to tune them down a bit.
