What do you guys make of my idle on cold start? It goes away after the car warms up and I assume the roughness is due to e85 and the S1 cams.. prob being paranoid but I am still trying to figure this car out.

Sounds like a vacuum leak.. I would check hoses

The cams and e85 does not cause the car to idle like that. I run more aggressive cams and e85 and I idle like stock without any sort of dropping in the RPM or any lope.

vacuum leak somewhere, check the vacuum lines. preferably the one that connect to the intake manifold.

I would also recommend to change the spark plugs and gap them within factory specs

Mine sounds exactly like that on cold start. It's so bad it stalls out. I've checked all the vac lines, even the ones behind the intake mani (Magnus v5). Have you found a solution?

idle surge during cold start. Set your Biss screw with the ECU in SAS mode. Also, make sure your IAC is still in working order.

Lastly, check for vac leaks.
