yeah mike, but it seems like the combo should be more like 625-650hp with what I have. I agree with the Mallory stuff. i'v had a earley hifire box that broke me down twice a Mallory fuel pump that gave me fits a Mallory unilight that the bushings wore out in no time flat, so I understand where your coming from. I thought the hifire6 was a nice box with a lot of features,guess not. my worst box was a msd digital6. I still have a Jacobs that works great.
