Holley sniper problems (1 Viewer)

Hey everyone!

Been a while, but want to report back. I’ve done two things to the 40 and it is running better than ever!

-Trimeki headers. These fixed my small vacuum leaks from the flange thickness.
-New o2 sensor. Old one was cooked.

Rock solid AFR and fuel pressure, IAC is good, RPMs do what they should. I’m going to pile on the miles now and hopefully let the sniper handle the fine tuning.

Best of luck to everyone getting theirs set up. Key is 100% no vacuum leaks, solid fuel pressure, and a functioning o2 sensor.

To add on to @Advrider639 comments, I just recently had issues with my AFR being off. Found that the exhaust was leaking through the heat riser bushing. Was able to weld enough on it to stop the leak and the AFR is back behaving as it should. These systems are great, but the slightest vacuum or exhaust leak can really affect it.
