Too Rich Couldnt Make Boost?

Hi all im a turbo noobie now :), but i ran into some issues this past week

For whatever reason my tune became fubar'd and i could barely build boost.When boost would start going positive 1-4psi, my wideband showed sub 8.5's and would sputter out.

I initially thought the spark plugs had met their maker but after changing them i realized that wasnt the problem. So with my very very very limited tuning knowledge i started making pulls on the street.(with no means to datalog!!!!) I did about 10 pulls mostly in 2nd-3rd gear and i managed to get my afr's from sub 8.5's to around 10.8. Now she pulls as happy as could be now at 10 psi,even stronger than before. Theres not much of a question in this thread, but is this a common issue when modifying turbo cars, has this happened to you?

Mods that matter:
jt56 bolton
rc 550's
walboro
aeromotive
maftpro with everything

Was your fuel pressure the same as it has been Aaron?

The colder air will affect the tune as well, but I think it usually makes it run leaner.

My fuel pressure hadnt changed.On the "old tune" i noticed the cold weather making me hit fuel cut

sounds like something got reset completely

My thoughts exactly.Now i can run it at 14psi with no fuel cut, before i could run 10 but 14 it would fuel cut.Im happy to say the least:biglaugh:
