Another new best time

Last week I ran a 11.843@114.88mph. I changed the jets in my carb going from 74/84 to 76/86 and picked up another 1mph. I picked up time and mph even though the weather was about 8 degrees warmer and more humid...also even had a slower 60' than my previous best run. I still need to get my 60' time down more so I can get into the mid 11's. I have koni adjustable 90/10 drag struts and moroso trick springs ready to be put on..just haven't got around to it yet. New best run stats.
60' 1.755
1/8 7.544@92.51mph
1/4 11.782@116.17

Heres a pic of my car launching from yesterday. I have a mpeg video of my best run but I don't know where I can upload it for hosting?

Thanks for the comments guys. Tires are 26x10.5 ET streets..getting worn out too, about 3 years old. I'll probably get some 28x10.5 tires early next year. 60' times are in the mid 1.7 to mid 1.8 range depending on track conditions. I still haven't raced on a prepped track with this setup so its always slick.
Carb is a ProMax 750DP which is basically the same as the Holley Ultra Series. It has adjustable air bleeds, emulsion jets, idle feed restrictors...ect. Its a great carb, helped a lot with the tuning after switching to this cam. It was almost undrivable with my old Holley 750DP but it drives great on the street with this carb. Heres a link to the promax website, my carb looks like the one in the top pic.
