Holley Sniper EFI - Competition for Fitech EFI.

We had one that lost a reference signal and shut down. We had another with issues following the target af at WOT. Cust service was slow but the issue did get resolved. One feature not to overlook is cold start tuning. Not all systems have adjustments for this.
Since we are a tanks inc dealer, we replace all tanks when we do a system. They are quiet and reliable.
