I am looking at buying 72-75# injectors, Should I get Delphi or Siemens? ECM mode?

What is the difference and which are better Delphi or Siemens?
I would like to buy the ones that are better for the street and that have more chips available for them.

Delphi
Flow Matched Sets
75 lb / hr.
Injectors
$57.50 each

Part Number 17113742 (OE # 17104988)
Static Flow Rate: 75 lb/hr @ 43.5PSI (300kPa) or 9.5gm/sec
Dynamic Flow Rate: 1.1 gm/pulse - 2.5ms pulse width and 10ms repetition rate
Coil Resistance: 2 Ohms / Low Impedance / Low-Z (Peak-hold ECM driver modifications required)
Cone Spray Angle - 22.5 degrees - single spray cone. Approximate cone angle for 90% of spray volume
Silicon grease supplied to lubricate o-rings prior to installation
Ball & seat design with 6-hole diffuser disc. Same as MSD and Holley product.


Racetronix
Flow-Matched Sets
75 lb / hr
Injector
$62.50 each

Part # 3145
Static Flow Rate: 75 lb/hr @ 43.5PSI (300kPa) = 788cc/hr (72lb/hr with test solvent)
Coil Resistance: 2.35 Ohms / Low Impedance (ECM driver modifications required)
Siemens low-Z injectors are able to operate at very high pressures with little or no degradation in performance.
Silicon grease supplied to lubricate o-rings prior to installation.


Also, who should I send my ECM to, to get the injector driver modified? I want the best place as far as doing good work and standing behind their work.
Thanks
Mike

Bob Bailey is the guy I had my ECM modded by....and I bought
Racetronix's 75 lb/hr injectors...doubt that either injecotr is better than the other.

You can also use the HighZ 75 lb injectors from RC Engineering and you don't have to modify the ECM. You can get these at www.forcedinductions.com

Forgot to mention, you also can get a better price on the LowZ injectors.

FYI, I have a buddy selling a set with very low mileage for $275 shipped, they are 75# Delphis I believe. E mail me at turbosam6@yahoo.com for info
