After 4 years, I finally got this thing ready to start. I start it up for the first time after fixing a couple of vacuum leaks and I can't get it to stay running. I need help. It will crank for a couple of seconds, fire and rev up to 4000rpms for one second and then immediately die. What should I mess with first? Also, does anyone know where I can get a flow chart for my 80mm Pro-M?

My point exactly. What values do I need to mess with to get this thing to keep running in startup mode. I've read alot since I posted this question. The crank settings are ok because it fires right up, but once it goes into the "startup" settings, it falls on its face. Even when I give it gas, it wants to die. Would my logic be correct in saying that this means that it is running lean or is it that the timing is off? The timing is at the stock 10*. Do the MAF settings need to be changed or should I look more towards the IAC settings?

Here's a few more questions for you...

Is your MAF calibrated for the 42s? Fuel pressure at 39psi with the vacuum off? What's the specs on that cam?

The MAF is calibrated for 42lbers and the fuel pressure is 39psi plus or minus 1 with the car off because I haven't been able to set the pressure with the car on. The cam has around 600 lift but the lsa is 113* I believe.
