With Holleys previous track record with EFI I wouldn't touch anything they sell.... You'll likely tell me about some magazine article you read that raved about how well the system works..... To which I'll tell you advertisers pay big $$$ to get nice things said about their products & unfortunately magazines need $$ more than integrity....

FAST EFI sells efi.. They don't have Holleys advertising budget so if you see an article it probably is an honest review....
