Hi All,
Anyone used a Holley Sniper EFI carb...... ????????
I'm thinking about it for my Sebring...... I only get about 130 miles on 11gallon of fuel (city cycle), this should improve dramatically, also better idle... maybe less heat under the hood as well and looks almost stock compared to a normal holley......... ECU is built into the carb

I had one installed on our 355 SBC last year and now my wife can start the car with no troubles but the mileage still sucks. I am thinking we need to take it somewhere it can be dynoed and tuned in.

I installed one last summer on my 406ci Chevy.  It made a world of difference.  I was fed up with constantly tuning (attempting to) my Holley Dominator.  The Sniper has brought out better performance than I ever had before!   One tip that I discovered early on - make sure you have a strong alternator.  It does NOT like voltage drops while running.  
The system learns as you continue to drive.  Once your desired fuel mix, idle etc are set, the computer does everything except the throttle! The system even controls my 2 phase electric fans.
