Holley Sniper EFI

I have read all the FItech reviews on the Facebook page. That's why I went with Sniper I thought Holley would have better tech-support. Holly has also sent me a TPS they said it should never go negative but it still does. Chevelle.com also has a good blog on Snipers and one of the guys there has my exact same problem he manually set some of the timing parameters and did away with adjustable rotor it seems to have fixed his that doesn't make any sense to me.
