gotcha

Hence why i was so confused.. air escaping the system means less air in the cylinders but the same fuel..

Where was the clamp you had to tighten?

When not under boost, extra (unmetered) air is sucked into the engine,it's not escaping.

Directly at the TB.

I think my pump is getting weak, afrs are slowly getting closer to 12's again. I might just do a pump rewire and install a walbro 400 or do a dual hanger setup and run 2 400's.

Yeah... That should mean running rich under boost, lean at idle and vacuum. :?

 

[IndigoMKII]

if it keeps acting up i will just go all out and build the fuel system i really want. dual walbro 400s atleast

Do a leak test on the IC pipes before you do that. Where there's one leak, there's more...
