Engine Masters just did an episode on it. They liked but as usual the devils in the details. https://www.motortrend.com/plus/detail/sniper-2-the-rescue/5222811/
It supposed to be better however i have the SNIPER 1 on my 68 and never had a Issue... the biggest issue was always the RFI interference which is mainly caused by the location of the ECU in the TB unit. well they didnt change the location but added a bunch of "insulation" there is a test of Engine masters : https://tv.apple.com/us/episode/sni...65ga4?showId=umc.cmc.cgbf45cp90jenwpxe19zdjqx i personnally opted for the ACEs KILLSHOT and it worked well: https://acesefi.com/products/aces-efi-killshot™-tbi-system?variant=42119454359758 here is another member using it succesfully https://www.v8buick.com/index.php?threads/efi-system-lead-aces-killshot.384332/
I had an original Super Sniper on my old car. No issues but didn’t have much time on it. I’m putting it on my new car and have updated the firmware and software to Sniper 2. There’s a SD card folder on the Holley site to down V1 to V2 on the original sniper.
