I hear ya. "If you did this or this you could go quicker." But like you. Mine is what it is. I'm assuming it has 14x32? 13x31 or 10.5W x 31 may be the next tire to try when these are done. That would put you around 7000 thru the lights. Heck mine ran 7250 with the 4.30. Now with the 4.10 it, around 7050. For sure it knocked .02 off the 60ft. It'll still go 1.26-1.27 on a good day. But it has been very consistant with the 12" wheels and 4.10. Your tuning journey is still very new. Maybe a touch more wheel speed. Your's recovers from 60-300 very well. It almost matches mine by 330 and even at 660. It took me years to get in the 9.0's. Pretty damn impressive. for comparison this was last year with the 4.30 in July air
