A while back, I replaced my stock fuel injectors (on my 350 TPI) with Accel 24# injectors. Since then, my motor has run pretty good. I have also added the minor mods in my signature as well as a 180 degree thermostat.

Since the factory injectors are rated at 21# and my new injectors are 24#, am I losing power and/or fuel economy by running the stock PROM?


Thank you.

 

It's hard to really explain to people, but even the stock calibrations for a stock engine are miserable, once you really know what good really is. Some of the OBDII ain't to bad, but the early stuff is crude.

But, the only way to get a chip fully optimized is by learning how to do them yourself. Then you can taylor the chip for best performance, and to suit your driving style.
