Aftermarket EFI systems what are you running

[liftlawssuck]

I have fixed/repaired Holley Sniper kits on a few cars and I have no problems with them. Most of what I see is from poor installations. Specifically grounds and shielding. When going this route with any of the brands is a different world. It is now all electrical. Troubleshooting and tuning is the same theory but in a different way. You need to be up on theory when going EFI. There is a thread in the 67-72 side going right now about someone going back to carb. Again I have no issues with Holley and it in fact wakes the car/truck up to a whole new level. However you need perfect clean grounds and shielding from EMI. These 2 problems are what most people I have talked to and what I have fixed are seeing. You fix them and you'll have no problems. I can't stress enough of a very clean install. Something you can get away with when going mechanical anything. There is a lot of cushion room with mechanical things. Electrical...not so much.
