backfire? like a giant flame pops out the back? lol, if so get used to it. The n/a cars ran rich from factory, and the un burnt fuel in the exhaust get ignited there and causes a giant flame. =)
im used to mine lol.

So... what exactly did you upgrade the pump & FPR to? And do you know what kind of fuel pressure you're running at idle?
My bet is that even if the FPR can flow the needed capacity, the return lines to the tank can't handle it. If you put a fuel pressure gauge in, I'd place money that you're running significantly higher than spec pressure at idle.
