Are you using the stock bypass valve that came with the KB kit?

 

[Sick 03]

yes why?

Is it going lean when you lose boost? did the kit come with a kb boost a pump?

 

[Sick 03]

i have a return style fuel system it does not go lean when it falls

what pulley setup are you running? its going to have some boost drop off in the upper RPM's, but should have that much, im wondering if its just spiking high because of the cold air, dropping to normal boost, then dropping off some.
