So I have been trying to tune a new motor. Rebuild 302, GT40P heads, GT40 intake, E303 cam, Pro-M 80mm w/ 30lb injectors, Paxton SN89 SC, and some other minor stuff. I have been having issues with timing and running right, just picking away at it.

Today, had it running and idling good, but when I let off the clutch it dies immediatly. No hesatation, not under load, it is out of gear, and I cant even keep on the gas to keep it running. Looked around but did not find post on this. I'm assumming it has to be something with the electrical and saftey switch, any ideas would be appreciated. Thanks alot

Are you running speed density? Did you upgrade your fuel pump? There are many things to consider...AF ratio? What temp plugs and gap? It really really really helps to get a dyno tune with a custom chip.
