What excactly are you talking about when you say its not being flashed as hard? I dont know how long you have been Drag racing but I will tell you this , I you have tires and suspension that will hook up and go straight and you are making more power at 4000 rpm than you are at 1100 you will absolutley get quicker ETs, as you will be leaving way harder. By the way Flashing the converter is when you accellerate against the trans brake [or foot brake in this case] from an idle to WOT and push it to its maximum stall speed. I install racing converters every day and when I order them I give very specific details as far as camshaft duration, carburater type and size, tire height, vehicle weight with driver, gear ratios, all in an effort to bring the converter in when the engine gets into its powerband. I am not trying to punch holes in your Flashing the converter theory, But I certainly dont agree with it.

Some think that a converter should stall a couple hundred rpms below tq peak but the reality is, more is better on the strip assuming traction doesn't become limited. A higher stall converter just becomes a little less streetable (I have been running a PI 4600stall on a blown 96Z28 as a daily driver until recently)
As for the slicks: Until you reach the limits of traction with the f1s you will only lose performance with the addition of ETs. They have a higher rolling resistance and that scrubs power as can be seen in the 1/4 speed. Think about it. IF you have 100% traction (no spinning) what does adding more traction do for you?
Brake stall that joker to raise the boost and power like they said.
