Stumble off idle

[1fastcobra]

Just finished my new setup
In my tta.
Front mount
80's
210-215 roller
1.7 rockers
Ported heads 175-155 valves
Ported intake
6776 turbo
3600 stall
70mm t.body & house
Car starts and runs good

Problem is when I snap the throttle at idle Under the hood quick
It Boggs a bit ( like the old quadraboggs ) then it catches it self

Looking for ideas on something to try
Blms are a bit high 141

Is the cam sensor 180 degrees out?

Not the timing gears the cam sensor. It needs to be set 25 degrees after TDC on the #1 cylinder compression stroke. I've seen people mistakenly install them 25 degrees after TDC on the exhaust stroke. When this happens the fuel injector sequence is wrong.
