Ok, I have tried just about everything and I am getting no results. Its a 2004 Cobra with a 2.9 Whipple at high altitude. It runs absolutely perfect when warmed up. But when I first start it up, especially after sitting for a couple days, its got a major hesitation when its cold when I blip the throttle from idle. I've tried messing with manifold volume, transient fuel, and Cold Base Fuel table with no results. After its been running for about 2-3 minutes and/or ECT is around 105 or higher it goes away.
The worst part is that I have to wait 24 hours or so between testing different settings. I've been pulling my hair out for a month.
There has to be someone out there that has run into this issue also and fixed it. Please help! Its so annoying.
