An older Race Systems chip was installed back in 2000.  I'd like to replace it with a more current chip some day, since there are many more parameters to adjust with the newer chips.  This chip is adjustable and is tuned on the dyno for an optimal air/fuel ratio.  I am running 42 lb/hr injectors and a Kirban fuel pressure regulator.  Fuel pressure is around 42 psi (hard to tell exactly due to the spacing of the marks on the fuel pressure gauge and the lack of increments), and the fuel lines and rails are stock.  A T-Rex external fuel pump is fed by a 255 lph in-tank pump.  I like to use a Wix fuel filter when I can find one. 

Cooling is especially important, due to the fact that I am also running the Vortech Power Cooler.  The Power Cooler puts its own heat exchanger in front of the engine radiator, so cooling is slightly impaired.  I did notice a slight cooling loss (3-5 degrees) before I removed the A/C, but since installing the '93 Mustang Cobra water pump pulley and removing the air conditioning it is not a problem.  The Cobra water pump pulley is smaller (see picture below), so it spins the water pump faster than the stock unit.  

I am using the stock water pump, an FRPP aluminum radiator along with a DC Control dual 12" fan setup and the DC Control fan controller.  I bought a unit that came with the DC Controller already attached.  (will be posting pics soon, see installs for pictures of the fan)  

The picture on the left is before I removed the A/C, the picture on the right is after.  I also installed an underdrive power steering pump pulley (below before and after), which raises the pulley side on the drivers side.  Without doing this or relocating the belt tensioner or something, the belt would hit the water pump pulley.  Now there is plenty of clearance.
