Sniper Backfiring with new intake.
I have a Holley sniper on a Pontiac 400. I just replaced the performer RPM with a single plane Torker II. It did not backfire with the Preformer RPM but backfires pretty regular with the Torker II. I do have controlling the timing but I don’t think it’s a timing issue, because it wasn’t doing it before. I know it’s a self learning system. Do I need to just drive it and wait for it adjust it’s self? I have about 20 miles on the new intake.

Update: Leaned out the AFR and it quit back firing. Everything seems to have stabilized.
