i tried adding a ton of fuel just to see what would happen. the gauge did exactly the same thing. it did get a little richer on the wideband but at the track i couldn't get it to go rich, it actualy got leaner. i did have open exhaust and more boost and with as much fuel as i programed in i thought the thing should have just dived over from being too rich and it didn't.
here is the really odd part. while the gauge doesn't move much my logging of the sensor puts the voltage all over the place. just going by the log i would say i am going under 50psi but the gauge doesn't show that. the log of the sensor is probably a lot faster than the gauge.
i am going to try one more thing. i just ordered the parts so i can plumb my two fuel rails in parallel instead of one into the other. if that doesn't fix me up then i will look into a voltage booster for the pumps or even a whole new fuel sytem with a larger feed line.

jim i have my fuel rials hooked in back of one to the front of the pass. side then the back of the pass. side to the return line i do see one side(driver side) running a little richer then the other side(pass side) but i am also running stock fuel pump i have not had time to put my fuel cell in with the
Aeromotive Pro Series EFI Fuel Pump
Product images may differ from actual product appearance.
For racers running high horsepower EFI engines up to 2000 HP naturally aspirated, and forced induction EFI engines up to 1450 HP, this is the pump for you! A state-of-the-art, patent-pending, ''dual chamber'' pump design, coupled with Aeromotive's famous proprietary aerospace composite technology, provides you with performance unsurpassed by our competition. This performance pump simply doesn't wear out. Flows more than 1000 lbs. per hours @ 13.5 Volts and 45 PSI. This pump features -12AN ports. The pump body is beautifully plated with an indestructible electroless nickel process. It comes complete with two -12AN tapered flare fittings and O-rings. It can even be used for limited street duty with Billet Fuel Pump Controller P/N 027-16302.
and the only reason i went with this pump is in febuary i am looking to put the turbo on with the l92 heasd and the tbss intake,and i am still going to keep the no2 as a 2 stage 225 are 200 shoot.
how long have you had the daul intank pump the pumps may be just lossing it in the upper rpms

might wanna check on useing the l92 heads with tbss intake. don't think it will work. the intakes on the l92's differ from the rest
