Can you turn up Electronic Fuel Injector Pump

[6.5SmokeStack]

Ok, I konw you can turn up manually injector Pumps, Can you turn up electronic Fuel injector Pumps? If so how, I would like to learn more on it, thank you

Yeah, it's simple! Buy a chip!

lol are you serious, or is there a different way, IM ordering the Heat sink and number 9 resistor, save money, getting Marine Injectors, and then maybe later on down the road getting the chip...

The number 9 resistor is what "turns up" the injector pump. Im sure a chip helps also too tho.

well that works for me thanks!

Those chips are a real rip-off..... Come on, $300+ for the electonic equivalent of turning a screw if you had a mechanical pump.... And they charge core too so it\'s not the cost of the physical chip either, as that\'s a seperate core charge most of the time...........

Comes down to the fact they\'ve got you over a barrel and they know it!

I feel the chis are over priced for the 6.5L also. But it isnt as bad as my friends 3.8L impala. Hypertech makes a programmer for his motor and wants a little over 400 bucks and the max power that he can get from the programmer is 15hp & 18lbs-tq. Its a good thing that his programmer can read & clear troble codes and erase his top speed limiter.

There are so many misconceptions in this thread, I'm not really sure where to start...

First, to torque454: the #9 resistor adds miniscule amounts of fuel, and is dependent upon the initial calibration of your IP. If you already have a #8 resistor, for instance, switching to a #9 will add such a small bit of fuel you won't notice it.

If you don't know how calibration resistors work, then ask and I'll explain... but don't just tell people that the resistor is what 'turns up' the pump, because that is completely untrue.

About the 'chip' comments... Matt, if your gramma's truck is a 95, you don't have to send in the 'core'. You only change the EPROM chip. in 96 and later trucks, you get a reflashed PCM, and send back your old one.

In neither case do 'they' charge a 'core' charge, so again, this is untrue.

Chip programming can address more than 200 variables and influences transmission shift points and line pressures, torque converter lock points, boost dynamics, injection curves and timing, and control of other PCM functions.

If you don't know how PCM reprogrammingworks, ask, and I'll explain... but don't tell people that a reprogrammed 'chip' or reflashed PCM is the equivalent of turning a screw on a mechanical IP, because that too is wrong.

PS - I'm really not trying to be snotty with this post, guys, but I want to reiterate ... if you don't know, then just ask. If somebody else comes along and thinks these misconceptions are the truth, they will act on them; that's why it's important to make sure you know what you're talking about when you give advice on forums like this.

In this case, it's only a chip debate, but suppose somebody gave false information out on how to fix your steering or brakes?
