FBO Systems

Whoever you are you have never asked for a refund or repair or you would have gotten it we have NEVER refused to repair or replace any of our products EVER.

Do you actually think that make the reluctors and pick-up coils? We do warranty them if you have an issue, all you have to do is ask, I've not heard anything about this.

6 years ago we tried your favorite HEI module, we made 35 of them and recalled them all and replaced with the HRR688 Microprocessor Boxes that we spend 5 years and 10's of thousands of $$ in development and they are flawless.

Run a HEI module on your test bench and you'll see that it doesn't miss fire it drops output starting at about 3800 as do all stock type transistor based Mopar ECU's and Duraspark boxes, hook it up to your test equipment and run it to 8000 RPM like we do on a full load bank and report your documented findings here.
