do I have enough fuel?

[turbowrenchhead]

I started to adjust my fuel pressure and watching my O2's. I start out with 780 mv. When I keep into the throttle they start to drop. All the way down to 690mv. And my block learn is at 105.

looks like time for a walbro 340 and hotwire kit.

ok look at my sig..

i have a 340 and a hotwire and mine has this problem

brent

Is a walbro 307 not enough? How much of a difference between the two?

307 will work just fine. Works strong for me.

The 340 is the same price and flows more - why would you go 307? Probably time for injectors too......

You think its fast now - wait till you put a pump in it.

either should work fine.if you're going to pay new money you might as well buy a 340.if you find a good deal on a 307,don't pass it up tho...

and yes,hotwire it.
