All,

In the process of tuning my Edelbrock kit with Zach from CSG. Everything is pretty much dialed in, but we have an issue with throttle transients from a stop. He has already removed over 30% of the fuel from the transient tables but when leaving a stop my AFR goes very rich for a second before recovering. This causes a very slight but very annoying stumble when taking off from a stop. Zach suspects one of my injectors may have a small leak since the fueling is dead on when driving normally. I'm going to get a pair of new injectors and start swapping them out one side at a time.

Anyone else ever run across this?
