Thanx for the info Todd I'm on it!

Will I'm running VP 100 I'm going to look at the routing this week.

Hard start can be a bit tricky. In the Holley, you have to get the air/fuel set somewhat manually with the IAC opening and startup fuel. The tables are based on CTS, and take some experimenting.

Also, the Holley has a fixed timing advance for starting. Where is that set?

I do have a gauge I just have to find out what the pressure should be. This Holley EFI is all new to me . Glade I have you guys!
