Power boost valve Vs Standard fuel regulator?

[mrzigazaga]

Hi Peeps...Just wondered if this would be worth while as I'm about to change a rising reg that i have on the car at the moment as i can smell raw fuel around it but have no visible leaks...I think some might be seeping through the rubber diaphragm, I have a couple of standard regulators but wondered if this would benefit me as it claims?..I do have an intermittent flat spot that happens very rarely although the car has been a lot more responsive since i cleaned the rocker cover breather, Flame trap, AFM and connectors, Fitted new plugs, Leads, Rotor arm and coil....Cheers...Ziga

Been done to death on here over the years. On a 3.5 your better off with the standard equipment.
Had a similar item on my original 350i. Sent it in for a tune up & after various trials it performed better with the original item in place.

A AFR gauge will help you no end, you can what changes are doing what, and eventually get it right, i got a boost valve some where you can have I used it on my Chim with success

Thanks for the advice...I may just stick to the standard for now then as I'm more than happy with the performance and don't want to start creating problems unnecessarily!.

I also had a friend driving behind me who said he could smell a very rich fuel mix coming out of the exhaust...Cheers...Ziga
