Great first post skid. Very good information. You sound like a common sense kind of guy. Please hang around here, always room for sensible members...
had pdi reprogram to 550 ecomy gained horsepower and fuel milage(1-1.5) will agree with pre post as 1200-1500 rpm seems to be best range
You can put the 625 in the ecm, or you can flash it to a 800 gen or military application or for that matter a marine 825. but without the needed iron changes you will not notice the diffrence. the injectors have a rated fuel limit. and the FRC will not let it meet or exceed that limit for that rated fuel injector. There is however programs that bullydog offer that help performance and MPG's. proven on a dyno
You can do it ive seen it done. But dont forget that the acert fuel injectors are pilot injection. And the acert requires alot more air to get a clean burn. you may have to use a mbn turbo as it spools up very fast. check with your local oem dealer cause cat will not like any info like that to get out.
