Did you dyno the TST stacked with EZ against the Red Line stacked with EZ? Im curious to know how much more power is available from the Red Line box at 100% fueling comared to the 63% fueling of the TST, with a timing box?

 

I ran the Redline stacked with the Drag Comp for timing. As of now at 600hp or over there is almost no power differences between the boxes. On a lower hp truck it might make a difference though. I have had no warranty problems with my Drag Comp but did with the TST( this is usually backwards compared to the norm though) Above 600hp with either a s.o. or hrvp vp44 I feel the condition of your pump will make more difference compared to the fuel boxes. We are just pushin the max fuel available from the vp44 and the pump is the limiting factor not the box. The highest power usually comes from fresh pumps. On the street in my truck both the Red Line and the Drag comp are much better than the TST. Tim
