Default New walbro installed,Car wants to die?

I just installed a new walbro 2 nights ago. Install went fine but now when I drive the car and slow down the car acts like it wants to die. I will be slowing down from 50-60, and not touch the gas, the rpms get lower and lower to the point where I have to put it in n and give it gas to keep it going.
It runs fine under load and while your on the throttle but once you let of and coast for a bit it starts acting funny, almost like its flooding. Do you have to get a retune with a new pump? I thought you didn't.

I am going to check my fuel pressure today but I don't think that's it because it runs fine under load.Any other sugestions?

mods are a 231/237 cam, full bolt ons, stalled a4, no2. It never did this till after the pump install.
I did run 2.5 gallons 110 race gas (went to the track wanted to spray) just after the install. Could that have affected anything?

Race gas...... most race gas by me is leaded. I assume that you would have checked this. If it was leaded, you probably killed your O2 sensors.
