How much have you guy's gained from a tune for spray?Ran a 10.6 @129 I made a bunch of changes without being retuned and think I have some more left on the table. I did a ported Fast 90/90, swapped out a set of SLP headers for a set of stepped Kooks and added a TNT kit. I ran the car today but had some issues with my x-pipe wanting to stay on the car so I ran open headers. I think this may have worked against me but anyway the car ran a 10.6 @129 with a 1.47 60ft. Not bad for the fist pass on spray banging gears. I think I will do better ounce I get the car retuned

You will deffiantly probrably have more left on the table. It's really hard to say how much since we have no idea how far your current tune is off. How much are you spraying? Car seems to run decent numbers for your mods.
FWIW: My car has always run it's quickest with open headers. If you weren't running extensions on them, adding them should help you out even more. I've always been real curious to see how an open X-pipe would do compared to open headers.

I only got to make one pass on spray, I sprayed a 150 shot . I know I can make improvements on my driving that pass and I need a retune for the Fast 90/90, rockers , and stepped kooks. It didn't help that there was a head wind going against us . Look at the awning in the tower from the wind on the video, you can hear the wind too. Were setting up another rental in novmber so the colder air and no wind with a good tune should help me out on improving my times not to mention getting more practice runs with the spray.

It is hard to say with the amount of info given. What I am saying is that you may want to record you KR and O2 counts. With that info it would be easier to see where, if any, adjustments are needed. From the looks of your MPH the tune must be pretty close as the car seems to have a good MPH for the mods done. IMO, the motor tune should be done for best MPH and use the suspension, gearing and tranny for ET reduction. Having said that if you don't see any KR and your O2's are good then you may be right on target. If you load a specific N2O tune in it and the MPH slows then you would be headed in the wrong direction. Information is the key here, record as much as possible and then go back and pick it apart before you make any changes. Hope this helps.
