My fuel pump went out. Does anybody think that my piggyback chip could have put undue strain on the pump and fried it?
I've had the chip for one and a half years.

 

I think it's just bad luck. the SRT piggy back is not that powerful.

beside, who here said the GS4 fuel system is good for up to 400HP?

I have not seen fuel pump problem before, may be it's just your luck, end of the year bad luck

 

That is what I would have thought-just bad luck. A thousand dollar "oh, I'll take that, please."

 

I haven't seen the GS with fuel pump failure either. But check all your wiring around the piggy bag ECU and the engine ECU and make sure all the wires are secure, no bare wire that touch another wire..just to be on the safe side.

 

Okay, I've had the car for 24 hours and the difference is plain silly. The acceleration is noticably quicker down low and in the upper rpms.
Clearly, for the last year I have had a fuel delivery issue. In fact, I believe this is why my dyno showed an insane amount of peaks and valleys.
I can't wait to do another dyno. Unfortunately now I'm running the stock iridiums instead of my TMs.
