My car never smoked while being turbo, but after I had put my car back to stock it began to smoke and bog down low.
Compression on my last test was 205 220 220 210 which seems fine to me.

My main question is if my aftermarket fuel pump could be causing my car to run rich.
The smoke seems to be white and my car stinks like crap.

I dont see how it could, but maybe it might be feeding too much fuel.

 

A bigger fuel pump will cause your car to run rich if everything else is stock, I would reccomend just putting the stock one back in.

 

So how does a S/C do it without running rich down low(idle). Does the FMU help out.

 

if you're fuel pump was tuned for the set up, than yeah it could cause it to smoke. just let your car run for a few days, if it still smokes than just take it out.

 

Oh yeah, its been more than a few days.
Ill just take it out unless someone else chimes in.

Thanks guys

 

fuel pump shouldn't matter unless your fuel pressure regulator is stock... compression on first cylinder seems a little low.

check to your ecu or piggy back. if it's white smoke.. your maybe running lean.

 

Its far from lean(I have a wideband hooked up). My exhaust tips are jet black and my plugs were wet when I took them out today.
Ran another test and 200-210 across the board so I'm not concerned about compression at all since its well within specs(28psi max variance between cylinders).
And yes, my regulator is stock(whole car is now).White smoke would more than likely be unburnt fuel.
I know my car is running rich, I'm just trying to pinpoint the problem.
At idle, my car see's 11.1:1 some times.
Just like you all have said, its gotta be the pump.

 

If you feel the need to go back to stock let me know. I am in need of a high flow pump.

 

I just read up on the fuel pump and its for sure the problem. When I get a stock unit in Ill let you know.
Ill give you a good deal.

 

Consider it sold!
