CONGRATS! you're hooked now!
I run the JR fuel tire that Jon recommends. but my combo makes a BUNCH of low end torque and hits the tire hard, so I started upping the tire pressure. I usually run 8psi, unless its a really bad track I'll go up for more traction. for your combo try 7- 7-1/2 and see if you get a little more wheel speed which might help with the wheelies, or lower your launch rpm, or add weight to the front end.
like the guys said, soft on the brakes, parachute helps.

7 psi was my sweet spot. Went up for more traction.

Jon Hansen, I have 31 x 12 x 15 Goodyears on it, and we were running them with 9 psi. Sounds like to much pressure. I DO have two more 15 pound weights for the front.

We went back up this past weekend, added 30 more pounds of ballast to the front of the FED, reduced the rear tire pressure to 6.5, and went 5.65 @ 125 mph (1/8th of course). So those changes gave us more than 2 tenths! 2 more tenths will get us where we need to be and possibly run NE2 at some point in the future! Now the downside... Metal in the oil.  :(
