I raced my tuned modded .21 this weekend it has just over a gal on it. During the quals it was running 220's then after the 25 mn main it must have. Broken in completly because power was up and when of came after the track after 25 min it came in at 175. I was suprised and so was my pit guy. I am having one issue that I need help with. After comming down the straight I hit the breaks go into the 180 and stab the gas and it bogs for just a sec. I changed the clutch shoes and springs. And it still does it. I am thinking it's a lean bog but it runs good. Good smoke and good power just this one area where power is not there 4 a sec. Any ideas top of bottom to lean to rich. Thanks.
