Cold idle issues

Hi Fellas,

I'm having trouble getting my car to idle well when cold. It seems like it now starts ok and will idle, but if the coolant temp is below ~160 degrees or so, it will run like absolute crap in gear (or stall outright). My tuner has messed with a bunch of stuff, and now at least it will idle in Park when cold, but the second I put it into gear it either stalls (or nearly stalls). If it nearly stalls, the vacuum disappears and my car will make boost at idle (since the bypass on the Whipple closes)...:doh:

Latest cold idle log and tune attached. THANK YOU!

Did it do that before the 112?

Do you have a bypass valve from whipple that is for big cams? I ran into this on a 2650/whipple setups with cams over 23x durations

@RadZ28: It did it with the 103mm as well

@Ben Charles: No, my tuner had suggested that as well but when I reached out to Whipple, they said the vacuum bypass valve that came on the Gen V kits is the only one they offer. If it would fix a lot of my issues, I would spend the money on the electronic Smooth Boost if need be.

Update: Ben Charles is working his magic, idle is vastly better and he's not even done. :worship:

I'll let him comment on what he felt the biggest problem with my tune was (that was causing the idle issue).
