I would like to know what is the biggest injector I can run with the stock PCM, WITHOUT AN INJECTOR DRIVER. Thank's J

 

racetronix i believe has an injector thta behind 60psi they are 92lb injectors

 

The biggest high-impedance injector you can find..



The bigest I've heard of are Racetronix 79 lb / hr injectors. You can find modified delphi's in the 80 -90 range, but I'd hate to try and tune those at idle....

 

injector driver is no biggie. got my 96# injectors running at 35psi static fuel pressure...easy on the pumps and fuel system and plenty of injector for big power

 

Amen.

My 96ers run waaaaay better than the Delphi 75s too.

 

So what's involved with the injector driver? Wiring, cost etc. Thank's J Also I will be running E85. I will start out with twin 255's, and if that's not enough I will swap a 255 for an A1000.

 

It's brutally simple Bro. Install took me 45 minutes and I hid everything. All you do with is snip the PCM to injector wires in the harness and solder one side to plug A into the driver box, and the other side into plug B. Then wire in amps and a ground, reset your injector tables to stock in the tune, dial in the correct size, and start it up.

As I recall, my injector driver was around $400 and in terms of drivability, it was the best $400 I spent on the truck (followed immediately by my Dr. X box for the 90mm).

 

WE offer the FJO injector drivers. Got them instock ready to go.

Thanks guy's ! So will the Injector driver idle better with low imp 96lbers vs no driver and high impedance 78's?

 

Absolutely. Mine idles better than 60lb High-z's.
