OK here is what happened, I launched in 1st gear every thing was fine, I shifted into 2nd and as I hit 6000 rpm the car nosed over.
I think it ran out of gas, I had the 76hp orifice in it at that point. I changed back to the 63hp orifice and everything was fine.
I talked to Eddie Salvo and he said to get a adjustable fuel pressure regulator and add in 5 psi at a time until the car stops running out of fuel.
Does anyone have anything else to offer on this problem. It is a CompUCar dry system, and works really well.
NEXT THING the fuel rail is fed from the front, the fuel filter hooks up to the line that goes to the front on the fuel rail, so why is the stock fuel pressure regulator at the back side of the fuel rail????
Does anyone know of a DIY site to install a adjustable fuel pressure regulator???? Thanks for I hope a lot of help here.

PS the car is a 1992 325i BMW E36 with a M50 engine. There is a Turner chip in it, tuned S/S headers, NO CATS S/S low back pressure muffler. A K&N cold what ever filter separated from the heat of the engine compartment.

I can only speak for my two m's.The stock fpr.is not adjustable they work with vac. and press.
Sounds like fuel starvation,but not lack of pressure If it was lack of pressure you would lean out and detonate like hell..
The only time I had that happen to me was when my bottle went dry with the wet kit and all the extra fuel fouled my plugs.
Are you spraying into the airbox or after the hfm.?

I think you first need to remove your chip, the way it increases power is through advanced timing. With the nitrous you dont want any advancement in timing as it will promote your engine blowing up. I think most adjustable fuel pressure regulators come with instructions and i think you just install it in place of the factory unit.
