My car has the smell of gas at the exhaust...n hesitates at around low rpm..but works fine at wot...u think running rich could cause this?

Your air fuel mixture is obviously wrong if your smelling fuel from the exhaust

#1 - 02 Sensor, #2 - AFM

but would this cause the low end hesitation?

It could, too much fuel could essentially choke the engine. I had an old subaru turbo that was tuned badly and it just fell all over itself until it got over a certain rpm

You haven't told us what mods you have. If you don't know, find out.

I would expect that with those mods you would need a tune. Ive been told by some people that the stock fuel pressure regulator can deliver normal pressure even with an uprated fuel pump but im not sure thats actually true.
