too much fuel can cause a power loss

[ivatu]

i have a problem with my fuel pressure because i have a fuel rail that doesnt have the fuel return line this cause that i have a high fuel pressure the question is to much fuel pressure can cause a power loss?

How do you not have a fuel return line? How did you manage to set it up like that, and why? This would mean that your fuel pressure is at max all the time whether at idol or at WOT.

I can't seem to even remember ever seeing any of the cars I've worked on without a fuel return line. You need to put that back on your car. And yes, more fuel means you will see more power loss of you offset the Air/Fuel mixture making it far too rich.

Of course. Too rich will make a big difference. I lean my chips out 2 points on the air/fuel. I run about 11.5 when stock is 9.5

Someone must have done a hack job on it at one point. You should go to the junkyard and find a similar car so you can see exactly how it should be setup and what may have been removed.

I agree, just get a bud or someone with the same motor so you can double check everything.
