off idle flat spot

[billet-boy]

Just off idle engine has a flat spot I have a fast classic system 70-s-.85 turbo and 83 lb injectors both were purchased from you. I raised the fuel pressure and it helped some. This is the first time using a fast system so I could be over looking something very simple. Some more info on engine ported heads and intake by champion, comp roller Hyd. cant recall specs on cam, and 70mm Acufab TB any info would be helpful.
